I was texturing a 4 floor building (quite large for a player) for a PC game in Substance Painter. But, no matter what I do, the texture of the walls seem good from distance and UGLY, blurry when you approach the wall. The texture is 2K (Unreal packed, of course).
I was considering whether to detach each wall of the building, so that each can have a 2K texture (4 walls with 4 materials). But, I’m worried about performance, texture streaming, draw calls and etc.
Any advice, guys?
