Syntax

virtual void EnableSecondaryTriangleBuffers
(
TUniqueFunction< bool *, int32)> SecondaryTriFilterFunc
)

Remarks

If Secondary triangle buffers are enabled, then we will filter triangles that pass the given predicate function into a second index buffer. These triangles will be drawn with the Secondary render material that is set in the BaseDynamicMeshComponent. Calling this function invalidates the SceneProxy.
