>>2935933thanks, I have Blender 4.2.3 so it does look different, not sure where I'm meant to edit the material in this; right-clicking in the top-right panel and renaming has no effect in Pmxe. Blender shows the correct color though (orange in left panel).
Maybe I'm proceeding wrong... I use MMDtools to create a new model, import the .obj, then attach the mesh to the MMD model. But somehow the material properties make it into Blender (both color and texture are correct) but not into MMDtools.
