Trying out the arbitrary mesh culling fun-ness with beta 13.
Has anyone come across vertical “stripes” of particles not being properly culled? Looks like triangular projections in Z. My mesh might not be entirely watertight, but it certainly doesn’t correspond to the stripes I see.
I’m working on making a simple repro case, but wanted to know if this was known.

Thanks Chad,
This is a known issue with our raytracing algorithm.
From our internal bug database:
“This is a known error with our raytracing structures. A similar effect can
be noticed when using high polygon matte objects, and also some
participating medium volumes. [Developer] is aware, and will fix this some
time in the future.”
As Dave said, it is a known bug. It happened with simple geospheres when I was doing the cheese.
It usually does not happen with boxes though.
We intend to fix this before release :o)
On a positive note, the effect of culling will be visible in the viewports in 0.9.14 (hopefully next Wednesday).

Yeah, I’m using a blobmesh to compensate for my self-intersecting collection of clip spheres and boxes.
When I was just doing overlapping boxes, I ended up with something like Duchamp’s “Nude Descending a Staircase, No. 2”
