use combined textures or not?

Hi guys, first post on this forum, noob question:

Is it better to use combined textures such as a roughness/occlusion/metalness single image?
or the engine take care of it during the build?


Hi Max,

Use combined textures where possible - You’re getting the same result with less texture samples, which is good news!

Also less texture memory.

You get artefacts if you channel pack uncorrelated information. Use BC4 format for single channel maps. Then you can set up resolution per map.
