In any engine, even good ol' idTech3, one can blend 2 (or more) textures via vertex color(s) - grass transitioning to dirt, sand to rock, etc.
Is something like that supported in Worlds? If so, how do I do it ?
Great question!
Currently this feature is not supported (AFAIK). Any texture blending would need to be created during the texturing phase before ingesting into Meta Horizon. Perhaps in the future we might see something like this though, so don't give up hope!
Happy creating!
Could you perhaps use the _VXM material type? That can blend between a textured material and vertex color values, not between two different materials, tho.

I thought about vertex color variants, but that's just that - solid color multiplied by texture.
I guess we'll wait and see what they announce (if anything) next month.
