🧵 Low poly UV unwrapping
Anonymous at Sun, 16 Feb 2025 18:19:06 UTC No. 1007603
I've been shittily 3d modeling for a while now but UV unwrapping has always fucked with me. How in the hell is the MG model nice and flat, but blender outputs my UV all fucked up? Do I literally have to go in manually and pin each vertex into the pixel perfect position? Am I just retarded and just not doing it right> Most tutorials that cover low poly modeling in blender just use minecraft square-esque models and shit so it doesn't help me out since mine are more triangular.

just, like, select a whole line of vertices you want to be straight and scale to 0 on the relevant axis

I had tried that but I assumed there would have been a better way to do it.

you're in low polyland. You dont need a fancy tool to interpolate millions of vertices into a perfect rectangle. You can do it by hand.

That anon is right, that's how I do it too. Around 1K or under it's very easy to just Alt + Click and S + 0 a couple dozen times. It's a pain in the ass and might take you a good 20 minutes, but it works. There are plugins that do that too but I've never used one so I can't comment on that.

Thanks. It felt hacky but if it works it works I guess.

You need to look into using different unwrappers from just the default unwrap, which is for organic stuff.

Like a cylinder unwrap will mostly correctly take care of of the arms and legs in your pic, maybe even the torso

If you absolutely want full control over UV unwrapping you can always do it with geometry nodes.
All you need is a 2d vector edge corner attribute.
Writing a vector to it will use the xy coordinate.
Also if you want to use cylindrical projection you can just make your model out of cylinder primitives that are already uv mapped, just move the uv coordinates to the right places.
This is useful for clothing where you want to make sure the texture follows the wave of cloth.

I mean if they want full control they do it by hand like explained, not through the whole geometry node rigmarole.

This is not normal anons, stop using blender. It lies, it’s not how 3D works and it shouldn’t take 20 minutes for UV editing. You’re wasting time and money.

Hmmm... I might try that. Can I get it for BLENDER??

Roadkill is literally blenders UV mapping code. I don't know about the paid version.
Blender has addons to straighten uvs that work like a charm
