Imported FBX Animated Model Has Extra Planes Added


Why are those extra planes there? In blender it looks fine.

Can you please share the blend file in this topic?

Also, I uploaded to Sketchfab and it looked fine. So there must be some way to fix it with code?

It seems to work fine if I export to glTF instead: itv.glb (18.9 KB)

It’s only necessary to play all animation clips at once to achieve the same result like in Blender.

If it’s a problem in the loader, it won’t be possible to fix it on app level. Maybe @looeee knows what’s going wrong.

I think FBX hates me : (

I think you might have hit on the same problem from this issue:

The FBXLoader doesn’t support polys with >4 sides. The code to split 4 sided into 3 sided was pretty simple, but >4 sided starts to get complicated. Also, think it’s only the blender exporter that allows you to export >4 sided. Maya and Max only export quads and tris.

Can you try dividing the faces in blender to 4 or less and see if that fixes the issue? Or share the ASCII FBX file here.

Ah yes, that makes sense. Let me give that a try and report back. Thanks for the help.
