I'm really trying to go deep into UVs and optimization, I want to save texture space with my models. Often time I have objects that just repeat themselves across my model (for example the rings of a chain), so I want for them to be unwrapped the same way at the same position on my UV space (this, I know how to do), since I don't need texture variations between them.
What is this technique called?
I know it's used over and over in games. Also, what is the workflow when doing this with Substance Painter?
If I have overlapping UV islands in Substance Painter I'm just gonna get glitches. Do I have to make a special model just for texturing it in Substance Painter, with only one instance of my repeating objects, to be able to create my textures?
If I understand correctly, they say to keep one object inside the UV space and move all the other repeated ones exactly 1 UV unit away (so basically, onto the next UV "tile") to allow for correct baking. I'll try doing that and will edit this post if it works, but even if it does I'm still very curious on what more knowledgeable artist have to say about this.
Hopefully all of this make sense, I'm self taught and kinda missing the proper vocabulary for this.
