Question by Kajan · Sep 24, 2015 at 08:52 PM · shaders optimization textures optimizing optimise

Optimize the standard shaders texture slots?

So my question is if theres some way to change how the texture slots is used. Since you dont need to whaste a whole RGB file on a grey scale texture like ao, roughness or metalness.

What we want to have is: normal map - RGB texture Albedo - RGB-A texture * and one texture with ao in R channel, roughness/gloss in B channel, metallness in G channel. And if needed emissive in the alpha channel

This will give you 3 textures instead of 5.
