I’ve been using Babylon File Exporter for Maya. But whenever I try to export my file as GLTF, some materials (that I didn’t add) appear in the hypershade window. When I delete those materials and try to export them again, those materials appear every time. This happens in every file.
I added hypershade window screenshots and a file with the same problem. I want to get rid of those materials, so how can I solve this problem and why is this happening?
