Fixes:

  • Regression in fbx with new indexer #44655 fbx files not working in latest release
  • previous behavior was culling scale values of 0.01 and det == 0.00004. which were valid in FBX land, det was not == 0, but in the cases of actual det==0 scenario which can be reproduced with node_3d_editor_plugin you can see it actually has a det == 0.
  • node_3d_editor_plugin was creating gizmos with transforms with det == 0, this is safe to do now due to this change, I have also fixed this for the gizmos but the grid still needs this to be done for it. This relies on absolute zero values to change visibility so I fixed this.
  • fixed fbx material mappings going to metallic property

I debugged this by putting checks on det == zero.
I checked bistro fbx and it imports fine, no dropped geometry anymore even with 0.01 scaling and det == 0.00004.

Current BVH does not really allow flat AABBs so this fix will do, but I want to replace by one that does soon so this fix will be irrelevant by then. I suggest lets just merge for now so things work.

@RevoluPowered
Fix zero scaling and material mappings being mapped to wrong fields
86c7faa 
- fixes scale values of 0.0013 (det == 0.00004) not rendering, they should render even at small values, but not at zero like the editor grid plugin supplies zero exactly.
- fixes node_3d_editor_plugin visibility bug when scale is zero
- fix culling with small scaling values - which are still valid to be rendered like 0.00004

note: grid is still not fixed, it has det == 0 issues but this fixes one of them.
