I've noticed EMBREE_BACKFACE_CULLING_CURVES works only for RTC_GEOMETRY_TYPE_ROUND_LINEAR_CURVE types.
Are there any plans to make it work with other round curve types? (eg RTC_GEOMETRY_TYPE_ROUND_BSPLINE_CURVE)
For now, I'm using an intersect-filter function to do the backface cull manually. Just curious as I'm sure the EMBREE_BACKFACE_CULLING_CURVES would ultimately be more efficient.
