This is one of the most useful tutorial ever seen until now. You speak clearly, not too fast, not too slow. There are many Blender's tutorial with guys that speak at not human speed in order to make the video shorter, but then is impossible to follow. Great Job.
Loved the tutorial as well; this is a huge help in getting boolean topology right. Don't really agree about the pace of speech -- thought it was way too slow -- but that's why CZcams has a Playback speed option, heh. :)
@@frenzofficial4418 if you use F in the example in the video, it would just bridge the two vertices with a new edge, floating on top of the face, which would cause more problems than it would solve. Using J is where it's at :D
Generally you don't want to be modelling like this at all unless it's absolutely necessary, time is very limited and you're scene is very small (And you don't intend to use this in any other sort of 3D application like a video game). Generally speaking you always want to avoid Ngons and avoid having unattached edges. From a visual point of a view an Ngon looks like it uses less geometry so it should be faster to render but this is the complete opposite. 3D graphic cards do not support anything other than polygons, so you're renderer has to then slice up the Ngon prior to passing it to the graphics card. This causes overhead vs if you had just made sure your model(s) were already well cut and modelled from the start, additionally you're less likely to see post-render issues and lighting issues as you're not relying on an algorithm that is guessing what you wanted to slice up the geometry correctly. Lastly a lot of other 3D applications simply do not support ngons because they don't want to deal with processing your model or will do so very poorly, this is very true for video game engines.
@@howdlej123 If you're just going for a render it doesn't matter. If you're working with game assets, animations or deformations, good topology is a must. Prior to the render, Blender converts all topology to tris, even if the entire object is quad-based, so there are conversions occurring either way. With all respect to you, and with some of your points being valid, I just don't think the statement "Generally you don't want to be modelling like this at all unless it's absolutely necessary" is universal. If you're using an addon like boxcutter and going for extremely complex hard-surface models with a nice render, trying to model off of quads and create all of those tiny little cuts and slices is borderline impossible, and even if you could do it would take an insanely long amount of time. For someone like me, who primarily works internally with Blender, booleans and ngons aren't a significant issue for the projects I work on. I can see where quads and good topology become essential, but it simply isn't required all the time and can be even more difficult working that way.
@@JoshGambrell My point was exactly as you said, yes this is fine if you're exclusively using rendering applications that will do it for you and you're not planning on using this in other applications. However, converting an Ngon to tris is not the same as converting a quad to tris, it's more intricate and can lead to unexpected results, simply put a quad is made up of 2 triangles, that is easy enough for a computer but an Ngon, as stated in its name is an N-gon. A polygon made up of N number of vertices, the more complicated that ngon is, the more time consuming it is and error prone it is for it to be converted into tris. I'm not stating that you must always model as if you're going to export it to other applications, especially not if you're a hobbyist or you know the exact use cases of your model, nor am I saying you need to model using only tri's but as a general rule of thumb you should model using a quad or ngon which is more easily divisible into triangles. Small models this is never going to be problem but this is about instilling good habits to beginners. There are plenty of 3D artists out there who get away modelling all sorts of things ranging from organic to hard surface modelling and do so fine without expanding beyond quads, this is because they may use ngons and sculpting to start off with but they well then retopologize later so they have a cleaner mess that is easier to export to other tools and production pipelines. Appreciate the reply, and I didn't mean to say you should never use techniques outside of the standard realm, just saying it's good to teach watchers the pitfalls and potential issues they may run into and why they may wish to use other techniques. I almost exclusive do hard surface modelling and almost exclusively use quads and I've never ran into a problem I couldn't model using just quads, yes it might've took some extra time to work the topology to look right but I know in the end I don't have to retopologize my model should I want to reuse it later in another application i.e for games. At the end of the day the use case will determine the techniques you use and for hobbyist this won't matter much, I just prefer to give people as much knowledge on things because not everyone looking for blender tutorials is looking to just render out things in blender itself.
Nah, it's only acceptable - if you are making visuals, movie shots. And you ahve small amount of time. it's better to spent 3x more time on model to get topology right. Then you ahve great baking, easier retopology and etc.
The "Weighted Normal" modifier does wonders for me. Some geometry just didn't quite flow right and this was just the tiny push I needed to make it beautiful! Thanks!
A good thing to remember, and what took me ages to understand, is that every boolean cut needs an edge to connect to. You can't have a cut in a face without anything to support it. Blender is absolutely terrible at connecting it automatically, sadly (why does it always pick the furthest vertex on a circle?), so we gotta make more geometry as support. Btw, dice in Hops is gold for this purpose. It doesn't care about ngons.
I've been using dice SO much lately. I don't know how he does it but the add on is simply amazing, finding ways around issues like this. That's why I wanted to make this video, so people could get the intuition behind boolean cuts,that way they will understand how to fix boolean issues such as artifacts :-) Thanks for the comment!
@@woolenwoods665 Hard Ops is a premium add on intended to hlep with hard surface modeling. Basically, it has a command called "Dice" which allows you to add segments kind of like a loop cut straight through the mesh, even if it's full of ngons. The alternative would be cutting straight through multiple times with the knife tool, and would take a really long time. Dice does this in seconds.

Wow thanks for making an absolute nightmare so insanely simple and clear. I had no idea a solution was so close this whole time, because I really didn't understand the problem in the first place. S-tier tutorial as usual!
Amazing tip! I use it a lot without really thinking about it when creating buses. To make cuts for windows, wheels, etc... Adding those extra lines helps a lot!
Josh, thanks for taking the time to create this video. I'm new to blender and am just discovering the world of "artifacts"and this was really, really, really helpful :)
Excellent video. It is nice to see someone show practical ways to fix these kinds of issues other than "make the bevels smaller", or "apply all of the modifiers and then fix the resultant mesh".
Great video man, for the longest I wanted to find someone who can explain in detail when some of these features do but also when and in which situation are stone of these good for. A lot of tutorial people never explain why we are using some of these tools and techniques and even more important, I love that you go in depths as to why things work, why they don't work, and what the remedy I would need. Understanding why things happen in blender and how to fix them or avoid them is super helpful. So thank you for this video, gave you a in like and subscribe brotha. I appreciate you!
wow you know what this really helped me understand a few more things about making models in blender ive only been doing this for a year and i really enjoy all of it but this was a big problem for me but it totally makes sense thanks for telling me about the weight normal's as well
Thank You Josh. Fantastic tutorial. I really like that you consider various scenarios, where resizing bevels or moving cutters around is not an option. There are a lot of tutorials out there that do not 'branch out' like this and I find your approach much more helpful.
This video was an absolute gem! I had a boolean problem exactly demonstrated in this tips vid and it has solved my problem! This is definitely one of the best problem solving tutorials I have come across. Brilliant work Josh!
I thought I knew it all. Thanks for sharing your knowledge. I actually learned something today. Normally I would just simple subdivide the cube before starting, but this is much more efficient.
This perfectly solves an issue this newb only recently encountered. Your straightforward tutorial led me to figure out exactly what the solution should be before you even applied that loop cut. Thank you, Josh. Keep up the excellent work.
Thanks for that! I had similar issues before to those at 7:45, and I tried to 'fix' them by adjusting the setting. I've never thought to solve the issue by adding a few edges.
Watched a few now, only come to find out about lattices, but left knowing so many keyboard shortcuts and other useful tricks :D Thank you for some very clear and well explained tutorials!
Love your tutorials. Such a great way to learn Blender! Curious if you could also do a tutorial expanding on this one where you fix artifacts on curved surfaces such as when you use a boolean through a sphere.
CAD software has its own demons (and only does a fraction of what a full 3D app can do). I've been using CAD software since the late 1980s and still do today. And I use Blender (and will continue to).
I like how you explain subjects in your tutorials simple and easy to understand and straight to the point, I learned a lot in Blender because of it. Hope you get more subscribers!!
1000 thanks- I started Blender with some years experience in 2D Graphics and Design, and still scratched my head about some graphics explosions... this one was a fantastic playground example.
Thanks a lot! Your videos help me immensely! I also like the way you explain things, it's so soothing (especially after a long maddening fight with artifacts).
God bless You Josh. U are the best blender tutor I have come across. You take You time to explain every detail of ur hard surface modeling.

sometimes it is enough to uncheck "loop slide" in the bevel settings
Much better solutions than the re-topoligizing I've seen elsewhere.
