i finished a stylized tree in blender, imported it in sketchfab, and the base color of the trunk is not showing properly, the leaf are alright, but small part of the trunk are turned green, the rest is uncolored, and the image texture is not being apply. I tried to import the fbx with the texture of the trunk in blender and it worked nicely, so it is not a UV problem. I actually have no clue on why this is not working.
Can someone please explain how this issue can be fixed?
