I'm getting a bit stuck here! I've uploaded so many versions of a model so far without any progression.
So i'm using archicad (on both PC & mac).
I'm using both version 20 & 21.
Previously (4 months ago) I uploaded .obj + .mtl + textures in a zipped file & it created lovely 3D models. Now though i'm getting a mix of either models with only a single material surface (white) or i'm able to get Sketchfab to recognise individual materials, but the textures are no longer automatically assigned.
I'm really struggling to find an easy solution to upload architectural models...
Any help or suggestions would be appreciated.
