Problem with Multiple colors in model materials

Hi i upload this model using Blender/Archipack
i replace all model materials by only two basic materials black and white
buf after upload to sketchfab i get multiple colors
glasses only have one face and there is no problems with normals

How many materials are you in “Materials” inside 3D settings ?

i got all 8 materials from the archipack addon + the 2 materials i created. But none of archipack materials are applied to any object

Could you to upload your model after deleted these 8 materials ?

How are the materials defined in Blender? We only support basic node shaders; any shader networks will likely fail.


maybe its the mesh… after export… arhicpack meshes are a mess… materials are principled
