Hi guys. Just a couple general questions regarding environment art. 1. I see people talk about using a “second UV channel” for things like rocks. Is this the same as just overlaying a tiling detail normal on top of your base textures in UE4? 2. When building modular, I see people say “it will scale up nicely” when using a…
I have heard about people using power of 2 grid because it makes all of your textures equally divisible, or because it maintains a texel density of 1 pixel per cm or something like that because it's cleaner but that goes out of the window as soon as you up the texel density so I don't know. I do know that you can set UE4…
1) Like Neox said the 2nd UV channel is usually reserved for lightmaps. Some engines create this channel for you and do an automatic unwrap of your objects which in most cases works just fine so you don't even need to think about any other channel than the first. The automatic unwrap will assume that every face is equally…
