Combined mesh vertices loose welds. #10

Closed ghost closed 4 years ago

ghost commented 4 years ago

Unity's built-in mesh combiner removes welded vertices meaning when a mesh gets sent to a DCC all triangles are separated.

This can be fixed in one of 3 ways:

-Create a custom mesh combiner that preserves welded vertices in MeshCombiner.cs

or

-Weld vertices after the flawed combine using probuilder (or custom weld method) in BuildModeUI.CombineSelection()

or

-In all live link plugins have the DCC weld vertices on import.

The blender live link should fix this, however it is still ideal to have this done inside Kitbashery.

The cause of this issue might not be Unity (or just Unity) but the OBJExport.cs script changing triangle winding order and breaking welds. A new mesh combiner that welds vertices can be found here:
