Unwanted lines/triangles after imported Collada model

Release Type: Latest official release

Version: 4.1.0.1374

Platform(s): Windows

Describe the bug There are unwanted lines+triangles(?) generated after I imported my model. Compare the video with the screenshot below.

This may be also the cause of a crash related for the physics engine.

To Reproduce Steps to reproduce the behavior: 1.) Use Model.zip 2.) Create a Model that uses the mesh in the link above. 3.) See video above:

(For the physics engine error) 4.) Create a Static collider from the mesh 5.) There are chances the game will crash at startup. Call stack below:

Expected behavior I don't expect the extra lines/triangles as shown in the video.

This is how the model looks

Log and callstacks Physics engine segmentation fault that happens sometimes when starting up the project.

I can't copy more details about the crash, for example the stack.
