Not sure if this topic should be in Rendering or Content Creation… I think Rendering?
So, I’m creating modular meshes in my 3D drawing application. Walls, windows, doors, etc. The walls give me some headaches:
Walls can be of different sizes, like 4 meters wide and 3 meters high. Or 6 meters wide and 2 meters high. They can be of any size!
The part that I cant figure out is the UV mapping and texturing. Independent of size, if I apply the same material to different sized wall segments the texture should be the same size on all the walls so the walls connect nicely. If for example the texture is bricks, each brick should be of the same size on each mesh.
I thought to ‘fix’ this in my UV unwrapping. I could treat the UV space as 1x1 meter. This would mean I need to resize the UV islands according to the size of the model. Island parts will become bigger than the 0…1 UV space. But I read that all the UV islands should fit in the UV 0…1 space. If this is true, then I should create a materialinstance for each mesh with sizing parameters? Or… ??
I’m a bit lost here. Does anybody has some advice on UV unwrapping, island sizes, making materials look the same size on different sized meshes?
