[TUT] Easy UV Unwrapping in Houdini

- This is the tutorial that I wish existed when I first started using Houdini. I was (and to some degree still am) extremely confused by the concept of UV unwrapping and mapping and I was unable to find any tutorials that would teach me a simple way of dealing with them in Houdini.
Please forgive my use of incorrect use of terminology in the video, I'm far from being a UV expert...but hopefully you can figure out what I meant!

Your videos are so damn clear! I don't know why that's so rare. Thank you for your awesome tutorials!
Огромное спасибо! Самое разумное объяснение по UV-развёртке! Очень помогла Ваша инструкция.
Thank you so much! I was clawing at my brain trying to figure out how to UV a torus for some Unreal Engine Visual Effects, this was exactly what I needed! Thank you!
Thanks! very nice intro to houdini UV mapping! helped me a lot!
Hello, nice and helpful tutorial.
Smal Update, since Houdini 19 there is a button on the right column of the 3D view on the lower end with small diagonal squares in decent blue and red, that you can toggle on and off.
When you hover over it, it says: Show UV texture when UVs present. So, you´re not necessarily need the Laps Visualize tool.
As always, there are many ways to get things done in Houdini.
Thank you this was so exhaustive!
I am a beginner in HOUINI and your video helped me a lot thanks a lot for tutorial keep posting.
Clear as usual. Tks
Thank you! This is a very useful video.👍
You're a star
You are the best. God bless you
nice tutorial, thank you sir !
Great video! Thanks
Thx, super tutorial
Thank you very much.
Very interesting
BLESS U SIR.
Thank You!
thanks, much needed.
Hi Right-Brained, Thanks for creating these tutorials. I've noticed that you also have some scewed UVs. Won't these scewd UVs give orientation issues with a texture that is used over the entire model? Perhaps my knowledge is lacking but wont these UVs scattered around give artifacts for lightmaps? Hope you'll find some time to respond and guide me in the right direction
Unfortunately there is no real replacement for manually creating seams and strategizing for a proper UV flattening based on one's own specific needs. UV unwrapping is the pain point of most modelers and texturing artists so in these videos I'm just illustrating a way of getting usable UV's without needing to do it manually. In Substance Painter I tend to favor using triplanar maps for repeating patterns, and then do manual painting and touching up as needed. It's not perfect, but it's fine for most uses. There is this app that I found out about recently, I haven't tested it yet but it looks like it can give promising results: www.quelsolaar.com
@@RightBrainedTutorials Trippy website I like it haha. Im glad you're show this workflow as I've always had in my mind that those scewed UV are somewhat useable. So the workflow sticks to getting those 3d models first, then texturing it. No procedural workflow after creating the asset within Houdini. Thanks for showing me that.
Hi, I have a model that I made in houdini which I'm having lots of trouble getting into substance correctly. Wondering if you'd be prepared to consult on it? Happy to pay you to take a look.
Hello Johan, are you on the SideFX forum? If you want to send me a PM there, my handle is Midphase.
Hi, I did the steps but the UV is not showing on the box. (grayed grids
with letters) used UV unwrap and UV quick shade node And how to tell
if your imported free obj statue in houdini has UV or not? Thanks!
You can tell if a geometry that you imported has UV's or not in two ways -- one hold the Middle-Mouse button and click on the File node, in the various Vertex attribute list there should be one called UV, if it's not there it doesn't have UV's. The other method is to hit Space-5 while your mouse is hovering in the viewport and it will switch to UV view, if there are no UV islands on there then you don't have UV's. UV Quick Shade node has been replaced by the SideFX Labs Visualize UV's node.
@@RightBrainedTutorials Middle clicked and it didn't have those keywords so I UV unwrapped and UV quick shade it. Is it the loop node that can allow all UV to be on the inside faces? ( after fracture). Or is what I did so far is enough to have UVs on the inside facestoo? thanks!
@@jasonjin3518 If you want to flip your normals to face inside, you can use the Reverse node to do that. As far as UV mapping, the textures should get applied to both faces automatically (but some maps will look weird if the normals are not facing the right direction).
Hi, a noob question here, what if the object is animated?
No problem, the UV map should "stick" to your geometry even if it's animated. Just to be extra careful, you can add a Rest attribute by using the Rest node.

Out of curiosity, what else are you looking to learn?
@@RightBrainedTutorials really thanks for sharing.
@@RightBrainedTutorials Thanks a lot for the tutorials! I would like to know more about how to set up and use multiple UV-sets in houdini. Another point I'm curious about is the project option "perspective from camera" in the UV Texture node. Thanks!
@@nininanyu I use the Project from Camera in this tutorial -- not a comprehensive guide but it should get you started: czcams.com/video/xgh5Vg3hqwI/video.html
