I have a model that looks great in the Windows 3D viewer,
but looks all shiny and bumpy in babylonjs. I suspect it has something to do with vertex shading. Is there a way to render the model so it looks more like the windows 3d rendering? I tried turning off mesh.useVertexColors = false, but that made no difference. This is what babylon renders.
Oddly, if I import this obj into blender and save a glb, then babylon renders the glb just fine, so what is different ? What other knobs can I try to fix this?
