Sorry if this already exists but I couldn’t find anything about it.
We are currently in the process of converting our assets from Unity to TreeJs and unfortunately, the texture structure of Unity seems incompatible with the Babylon exporter.
Namely, in Unity, the smoothness map is included in the alpha channel of the metallic but when I plug it in a physical material and tell it to only use the alpha as a the regular output, the exporter still creates a trasparent png with 3 identical channels in R,G and B instead of copying the alpha in the green channel and collapsing the rgb in th Blue one.
(I hope my description is clear, I wanted to include the resulting png but I’m only allowed one media)
Am I missing a secret checkbox somewhere ?
here are my current options for the bitmap in the material editor
