Multi-Channel RMA texture support


(Ironbelly) #1

Currently it’s standard practice in the Games industry to pack in the Roughness, Metallic and AO into a single map, each on it’s own channel to save memory. There doesn’t appear any way to get RMA maps to work properly in sketchfab and define which channel is which which means we have to export all of our textures for the game engine and then export them all again for Sketchfab with each separate texture being in it’s own file

It would be a big time saver to be able to utilize RMA maps without having to do this

Interesting, is that using in house tools, custom software export or it’s directly in commercial software ?
If the latter, can you provide list of software supporting RMA format ?

Unreal 4 and Unity support this
