[bug]Triangulation Problem

[Zom-B]

Hey Ono & Ben...


I have here a scene that gets some wired triangualtion, kd-tree or bvh doesn't matter...
it looks for me like a subdiv generated fault.... but no subdiv on this mesh!
It also doesn't seem to be a problem of scaling!

1.1.18



2.0.9


Th Fun starts that this error seems to be generated by the camera setting! I can soo into this (just like done here) but with other camera settings everything seems fine...
I hope the simplified scene file helps ya!

View dependent subdivisions are linked to some camera aspect, notably the position and frustrum. It seems indeed that there is a subdivided mesh, probably using a curvature optimisation. The black triangles suggests maybe that two meshes are present. My guess

no Indigo based subdiv is going on here!!!
only one mesh...

Indigo 1.1.18 vs 2.x

check the scene files

Oh yes I missed them, and the images were eloquent enough. I was too keen to speculate on the issue I think
