Relief Maker solo te da buena vista del Relieve mas no buen acabado porque el relieve lo hace distorsionado solo alisa los bordes del relieve y se ve bien pero si fuera a producción no saldría bien a comparación del relieve de Zbrush que si mantiene la forma del relieve pero es muy bajo. Busca Add relief Blender me pareció muy interesante el relieve que genera es un tool de pago.
Are you using the make bas relief function in zbrush or just grab z-debth? there are a lot of settings on zbrush's bas relief pannel you aren't addressing it seems which would vary to results greatly. I'd also be tempted to see what i could get out of capturing both relief and zdepth from zbrush and blending them manually in photoshop or just by morphing between them on layers in zbrush.
I've been using the bas-relief function in ZB since it came out. The settings adjust the fine detail and draft angles of the relief, but they don't change the underlying structure. I use depth maps a lot too, but only from my own relief sculptures. Neither ZB or Relief Maker creates 'proper' relief, but they can be handy. RM has the edge though, defintely.
One more question: at the end of finishing that bas-relief, would you be able to cut it in two or three (or any number) equal parts and use those parts as individual pieces/parts in other projects? Something similar to making a large cube with six different bas-reliefs on its six sides, and then cutting this larger cube in 4 x 4 x 4 = 64 smaller equal cubes, and saving each little cube as a separate part. Then you could 3D-print all the 64 smaller cubes, and make a game out of it for someone to reconstruct as a 3D puzzle game. But it all starts if one can cut the initial large cube in smaller individual cubes. I am not sure I described the process well, sorry if that is the case.
I think I understand what you mean. There's no reason why you couldn't apply reliefs to the sides of a cube in the way you describe. The only issue might be that as each individual model is very high poly, you might end up with an unwieldy project. There's several ways to mitigate that, though.
@@mattbonaccorsi Is there any tutorial out there that shows how to take an already made object and cut it in pieces, so that you obtain as many new parts as you want out of it? Is there an existing function in ZBrush (cut?) or this is what you meant by "mitigate" (use other procedures to obtain the same effect)? Thank you thank you!
I am really impressed by this feature, it is really awesome!! Is there any free ZBrush app out there, be it only bare bones? I would love to learn this, but I am broke, and too old to start a new carrier, but I would love to be able to create bas-reliefs/semi-reliefs/alto-reliefs and import them in CAD! I am also not working professionaly in CAD, just a hobby that I picked from CZcams on my own, I just watched hundreds of video clips and got on with it so well that now I am reasonably efficient in CAD.
You can try Blender, which is free and has sculpting tools, or SculptGL, which is perhaps a bit easier to learn. It's also free.
@@mattbonaccorsiDo you happen to know if currently Blender has this "Project BasRelief" facility/tool to take in a 3D scene/model and make it into a basrelief? Or is there any similar procedure that one can apply in Blender to achieve this, even in multiple steps?
@@straightlevel.cruising2644 I think it's only ZB that has this feature, but there are workarounds. You can use Blenders depth and mist render passes to make a relief map that you then edit in a graphics package (if need be) and use as a displacement map to create your relief. It's convoluted, but it works.
I have a question if you can help me... I want sculpting and export normal map for my low poly to unreal ungine this is normal ? Or use decimation master !!!!
Hi, I can't really help you with that one. I don't work with normal maps at all. I sculpt for CNC, so all the detail stays on a high poly model. I don't make low poly versions. I would take a look on the ZBrush forums. There's probably information already on that topic.
@@mattbonaccorsi thanks
Hey, This is something i find very intriguing i see your background is always in the coin shape. would it be possible to remove the excess from the models once the bas relief is applied so its its just an outline of the model ?
Once you've completed the relief sculpture, there's several ways you can remove the background. When I'm working straight from reference artwork (rather than playing with the project releif function), I tend to mask off my working silhouette first, then sculpt within it. This means I can use deformation to add a slight platform to the model, which is necessary for coin dies, then create polygrouyps from masked, and delete the background area.
It is scary how fast things change. The need for creativity will never go away so don't worry too much. Questions as I'm new to Zbrush. The plate background you are using. How did you create it? What is it called in Zbrush? Thanks!
Hi Paul, I agree with you, but I think designers and artists will have to change their definition of what creativity looks like. I spent much of last year teaching on a graphic design degree, and ai is definitely a threat to 'decorative' design. I spent a lot of time teaching my students to leverage their conceptual skills in terms of symbolism, satire, inference etc. It's the human connection stuff that AI can't do. Regarding the plate. It's one I made myself so isn't in the zb defaults. I wanted something with no back mesh, and a particular separation between the resolution of each subdivision. I'll upload it to my site and post a link if that's helpful.
@@mattbonaccorsi wheres the link lol
@@user-oe1vb2jd9u Apologies - I forgot! Just added it to the video description.
@@mattbonaccorsi thats amazing! thank you i still have a long learning curve for zbrush but i'm having a good start
This is cool, I think the artefacts appear because the pins are not as tall as the deepest part of the underlying relief? I like the elegance of the idea,
thank you
Amazing.Would you please make a tutorial video of how to sculpt these coin bas relief
I wasn't lost until he said "Control + Zed" instead of "Control + Z"
It is only one tool in a tool chest. There are many tools out there and none are perfect. Demand might be reduced but the need for artistic interpretation and skill will still be there. Though the Zbrush bas relief projection is pretty dang good.

s. Thank you In The setup❤️
At least here it is.
Are you planning on making a tutorial on how to sculpt using a reference image?
Sorry for the delayed reply. I have many plans for tutorials, but life and work keep getting in the way! If you're interested, I'll put together some vids about 'proper' bas-relief sculpting...
Just getting into Zbrush and nothing I do makes the basrelief. I'm new to it all so could you do a vid going through your setup, what's where and walk us through it step by step on how to make a coin and do a bas relief on it? That would be super helpful. ❤️❤️❤️
Sorry - I missed this comment. Notifications weren't switched on! Are you looking for help just on using the ZB bas-relief tool, or are you talking about coins in more general terms? Sculpting bas-relief from scratch is quite involved....
@@mattbonaccorsi just the bas relief won't work. It doesn't apply a relief, just outs the model onto the coin blank. But yeah coins in general would be great. I'm trying to make some to CNC machine for my D&D group.
@@jamieskunk Could you drop me a screenshot of the result you get? It's easier to see where the problem might lie. Have you got any designs for your d&d coins? It might be easier to do a walkthrough with one of them.
@@mattbonaccorsi ill try get a SC over tomorrow. One side was a bust. I was going to use one of Franz Karfka as it's linked in to the sessions and on the otherside like a D20 or depending on size of the coins add a few different dice types. I dod the brush capture thing but when I press and drag on the surface it just adds the bust/model. I practised with a free bust model of a random roman woman before buying the kafka model.
@@jamieskunk The bas-relief projection tool isn't click/drag so it sounds like you're using a different function. If you got 2 subtools - a flat plane as a background (with a decent level of polygons), and your bust aligned in front, you just have to select the plane and then hit the 'project relief' button. The relief projection settings and button are located on your tools panel on the right side of the screen...
Danny is a genius
Hi, what is your settings for the base mesh cylinder? Thanks a lot!
I use a flat plane with 3 subdivision levels. 500k, 2.2 mill, and 8 mill polygons. I do most of the detail work in the second layer, and use the top layer only for very fine lines or for polishing surfaces.
is the highest point of the relief actually the nearest point to the camera in the model?
Yes, so it's still not a perfect bas relief, as it doesn't know to cheat. It's good at analysing the 3D model and pressing it flat in a sympathetic way, but that's all.
@@mattbonaccorsi its still looks off to me that the left knee of the girl with the sword has such a high depth.
but there is also a new option on the left side for bas relief producing a relief you can drag around, maybe this would work better in this case
Как красиво! Спасибо!
I'm a coin artist too and that is a v powerful tool for creating layouts with multiples characters. Thanks for sharing. db
do you have a suggestion on how you could quickly remove the background so the objects you projected are pierced through without a backing but still have the depth of a bas relief
One off Pixologic's reveal videos showed an option to automatically mask off the projected relief. You could use the mask to clip the relief from your background. I'll try and find the vid again...
@@mattbonaccorsi thank you
I see you have the background mesh up around 20meg and then you have to deal with it to get something useable. After days of playing I think I will have to wait for some magic to come along.
I have a template mesh that I tend to use - it has 3 subdivisions, with 3 million+ish) polys. I only use the highest sub for things like this, so I get the highest detail. I do most of my work in the middle sub. As everything goes straight to CNC, the topology doesn't really matter as long as it's reasonably uniform and dense. My biggest issue with the relief projection is the high jagged set edge, but that might just need some playing around with settings.
@@mattbonaccorsi I know this video is old, so I'm hoping you still read this, but when you say you send this to CNC, do you send them an OBJ or do you convert this to a CAD file somehow? I'm really interested in machining sculpts and so far I've only found that I would have to do a base model in Fusion, export it as an OBJ, bring it into ZBrush, then sculpt, bring it back to Fusion and do a conversion there. Maintaining quads all the way through is very important from what I see. I'm just wondering if there's a quicker/easier way to get a STEP file for machining directly from ZBrush. Also, if you can directly mask the relief, have a look at this video for some tips about smoothing out the edging that it produces - czcams.com/video/RByXIvjcS7U/video.html
@@CRyanBurg I usually export an obj or stl file that gets imported into a package called Carveco (it was previously known as Artcam). Most relief CNC machiners and mints use this software as it's designed very much around producing 2.5d products. I think that the issue you're going to run into is trying to get STEP files out of a polygon mesh. There are 2 basic approaches to 3D modelling - polygon and NURBS. Polygon modelling creates a 'net' of triangles (or quads) that is distorted into the required shape. The more dense the net, the more detail you can achieve. NURBS modelling uses a mathematical approach to simulate 3D shapes rather than a 'net'. Think of the difference between a jpeg and a vector graphic. The advantage of NURBS is that you can be very specific and accurate with measurements as the model will not lose integrity when scaled. The downside is that it's not very good for organic sculpture. Polygon modelling is great for organic sculpture, but lacks accuracy due to the high number of polygons needed for close measurement. Converting a polygon model to a NURBS is tricky. There are methods of translating Polys to NURBS, but they usually involve converting each polygon in a model to individual NURB triangles, which makes a huge, unwieldy file. The only software I know of that works well across both processes is Rhino, which is used by a lot of jewellers as they need a blend of sculptural freedom and engineering accuracy. If you're having success importing obj files into Fusion, then the simplest process is to do all your modelling in ZB, and then just export the final file, rather than jump back and forth. Of course, it depends on what kind of sculpts you're making....
@@mattbonaccorsi Thanks for the quick response. I'll definitely check out the Carveco software. Sounds like what I might need for doing coins. As for the other stuff, I'm aware of the difference between the types of modelling and each others shortcomings. I do most of my poly modelling in Blender and jump in ZBrush for details and such forth and then project those back onto different models/maps depending on the need case. Down the road I might have to created STEP files that have a ton of details like engravings and fancy embossing. This video has given me an idea of how to get sculpt details into STEP files by using the Project tool in ZBrush to project on to a subdived quad mesh that is exported from Fusion - czcams.com/video/eQ7QgAyTOOw/video.html. It seems like it takes some time, so perhaps the models will need to be broken up into smaller parts and then rejoined somehow for machining.
@@CRyanBurg It would be helpful to get some idea of what you're trying to make. You mention making coins, and that's what I spend 90% of my time doing. I wouldn't consider using a NURBS package to sculpt anything up other than lettering and rim profiles (tbh, I do most of my lettering in Blender). I've used Blender to convert textures to mesh before. It's useful in the right context, but easier in ZB because you can really boost the poly count to get the detail, then decimate it back before exporting so that it doesn't take an age to process. I model at about 3 million polys in ZB, and then decimate to about 700k before I export. Keeps the detail but loses the file size...
I hope they will enhance the projection result in future versions........those three sliders are not giving expected results yet
Can you post an image of your result? I'm interested to see what you're trying to do.
@@mattbonaccorsi It only makes shallow reliefs.....if i make z-depth more, the result is not acceptable.
@@cnu73 I see. I like the shallower effect as it works better for coinage, but I can understand your issue...
Thanks for posting Matt
Out of a job? Ha!. Tools don't have the ingenuity to use themselves ... they need a human attached! Sounds to me like you're already adding the human element to the new tool. Anyway very interesting, especially listening to an experienced bas-relief modeller. Cheers. Oh, and glad you're recovering from Covid. Hope it wasn't too distressing.
Thanks for that comment - much appreciated! Almost back to normal now, although my sense of smell is still 'lacking'.
CNC modeler here....... the results what zbrush provides as of now when I hit Project Relief button is not acceptable....it is still very primitive. Should wait to see if it gets enhanced in future versions. But it will be helpful to build from 3d model.
What settings are you using within the 'project relief' box? I've found that the quality of the projected relief depends on tweaking the settings, but more importantly on the resolution of the projected mesh, AND the plane onto which you are projecting. I project onto a base mesh of 3 million polygons, and it works pretty well.
@@mattbonaccorsi repeat count - 1000 contrast 1 , tolerence - 0 radius- 0 , then used Adjustlast slider ............
@@mattbonaccorsi Base mesh about 1 million poly
@@mattbonaccorsi the issue is, grabdoc gives good results at higher z-depth and this new bas-relief is only to make very shallow models, i.e. 100:1 ratio
I hear you. I do a lot of 3d cnc carves, and have squished models down to do similar things. At first I was really excited about the new bas relief tools,, but then I realized everybody can do it now, lol. Looking forward to your next one. I'm interested in the 3d from photo software. I'm not a good sculptur, but I like art, and have been studying zbrush a long time.
I used to generate base mesh from photo using alpha. Then sculpting on that base mesh is much more easy and efficient
True, I've done that in the past too, but as it only takes me 3 hours to create a sculpt, the time saved by using alpha isn't worth the loss of quality.
Amazing work! What is the maximum height/dept for your low relief sculpts. I am seeing .3mm to .5mm so wondering if you have anything specific you target? Also do you CNC or 3d print this to get maximum detail?
Thank you! I work mainly for collectible coinage, so the most common size is a 38mm diameter, with a maximum of 0.35mm relief. The designs are usually CNC/laser engraved as dies (3d printing doesn't capture the detail) for striking. As the products are struck, there can't be any undercuts on the model.
@@mattbonaccorsi Very cool! Is there any kind of post processing like polishing involved? I am wondering if such small detail and survive any kind of finishing work.
@@ikbo Traditionally, the engraved die would be hand finished to replace any fine detail lost 8n the process (I originally trained as a hand engraver and die sinker), but modern CNC and laser machines are so good at maintaining detail that it's not really necessary anymore. Some of the smallest coins I've worked on have relief scales of around 0.08mm, and its still visible on the struck coin. A lot of that is down to sculpting so that light bounces off the model in the right way and highlights the detail.
This tutorial saved me a lot of frustration, thank you :)
Sir can you teach me zbrush for coin portrait designing
Owen showing Larry his coin collection was a lovely and touching little moment.
Dude that's awesome
Great job! and beautiful music. Thanks.
This is very nice, however a little explanation on the tools you use would've been nice
I use mainly 'clay tubes constant' for doing the bulk, then 'hpolish', 'planar' for smoothing out the planes, and 'damstandard' for detail. I have several damstandard tools with different alphas, based on hand engraving tools that I used to use.
Please provide me low speed play video because I didn't understand which tools you using
Where did you get such a nice scan of a coin like this? Or did you scan it yourself?
Hi Richard, Scan came from the customer. It wasn't actually that good, which was the reason for the video in the first place. I'm not sure if it was laser or contact scanned, but in my experience, the best scans usually come from contact probes such as made by Renishaw Renishaw.com). In cases such as this one, I usually remake any lettering/ geometric features from scratch.
Sir how given sharpness and smoothness in this STL.i tried according video but didn't sharpned
The video shows you how to reorganise the polygons so that you can sculpt in detail. This process will not sharpen the detail for you. You can sculpt on the portrait to add detail, but to make the letters sharp, you must create new ones.
@@mattbonaccorsi can you guide me how make new letter and how to set same position position of stl file
@@sonuverma2796 Sir, we have had this discussion. To guide you in making new letters, I will also have to train you to use the correct software. This would take to much time, and be very expensive. My advice is to obtain a copy of Inkscape and Blender (both are free). There are many tutorials online so you can become familiar with these programs. When you understand how to use the software, then it will be easier to explain how to make new letters.
Sir can you make video for me letters designing and set letters actual position
@@sonuverma2796 Please understand. I cannot create a video of this for free, as it will take a long time to make. The process cannot be done in ZBrush alone. You will need 2 more programs to do it.

Owen's memories of his father. One of the sweetest movie moments ever.
This scene always always gives me the manly blinks.
It makes you feel sorry for Owen.
awesome job! thanx for posting this vid! I would live to see a silver 3d print of this!

This is a great scene. People keep things for the memories that they represent not always for what the items are. This illustrates that point beautifully- it's actually funny because the coins have really only face value but Owen doesn't see it that way. They are connections to his father. Love it!
