How get mtl file to also load with obj file

I export a modified file from Blender as waveform (obj). The download includes two file .obj & .mtl. I can also download as fbx which is supposed to be a “combine.”

So, when image is viewed in the viewer only the mesh and the “white” wrapper is displayed. I have tried everything but I cannot get the mtl (skin) file to apply or be visible.

What am I failing to do properly?

Well I figured out a simple way to upload a functioning model from Blender into Sketchfab. Simply Save the Blender model whcih will have a .blend extension.

The model.blend can be uploaded to SketchFab and will render properly. Mesh AND material “skin” will display properly in SketchFab.

You can also just put your obj and mtl in a zip and upload that–this works if you have texture files as well.

Thank you. But when I zip up a folder with obj and mtl files , Sketchfab only shows the mesh and the white “skin” not the model “skin.” From Blender, I only have success with importing the .blend file.

If I export as obj with mtl files , I do not have success.


Ok if your material has anything more than solid color, then you might need to UV unwrap your object and bake to one or more texture maps.
