More than doubled the speed of the MeshTrimmer stage of HLOD generation Only readback the texture once, not per ray Neighbouring tris now start with the successful ray of the previous triangle as that's likely to be valid Do the dot product check before the ray, halves the number of rays Removed a bunch of allocations (it's editor code, but still useful) Full S2p with HLODs: Launch Site 9:33 -> 2:18 Water Treatment -> 2:23 -> 0:51 S2P Launch site
