Hey guys. I have a problem on my game, draws calls are much and reduced FPS. However i already know solve de problem, with Texture Altas and UVs, but i am confused, i already search in google for defenitions but i stay more confused, Texture Atlas and UVs don`t know the same thing? or which one requires higher performance in the game?
I hope for answers, thanks.
A texture atlas basically means you use a single texture for multiple objects. If the objects are 3D you just need to unwrap them together.
In 3ds Max (or whatever application you are using) select the objects you want to have on the same texture, drop an UVW Unwrap modifier on all of them and unwrap them together.
If they are already unwrapped it's even easier. Just select all of them, drop another uvw unwrap modifier on them, delete the previous unwrap and use the Pack UVs function.
