Currently, Cesium discards degenerate triangles in the function
BuildChaosMeshTriangles
inCesiumGltfComponent.cpp
.This causes collision to not work for the discarded triangles.

As described and discussed with @kring in this thread on the Cesium community forums, there might be cases where users would want to enforce that these degenerate triangles are not being discarded.

This pull request is a naive approach to adding a boolean option to the
Cesium3DTileset
actor which a user can activate to enforce this behavior.Most likely this is not a sensible solution to that issue (dragging that boolean through ~5 different functions seems a bit excessive) but it might serve as a starting point.
