- raytracing code now uses cylinder-line intersect for strands. It used to intersect with the screen-aligned strand quads, giving too many misses for tracing. Note; mirror for hair is still not well supported! - added in Materials a choice for whether a material is Traceable for raytracing or whether it is part of Shadow buffers. This way you can exclude hair strands from raytracing, but still get shadowbuffers for it.
