I’m experiencing crashes from calls to rtGeometryTrianglesSetVertices. In the verbose output I see the following text, but then the program exits unexpectedly with no error message and a non-zero return value.
INFO: Program cache HIT : aabb_indexed_100_000 INFO: Program cache HIT : intersect_indexed_100_000
Sometimes I can get the program to run if I delete the OptixCache directory, but this does not always work.
I am sending traces to the help email.
The environment is RTX 8000, Windows driver 418.81, nvcc version 10.0.130
There is a third behavior that occurs sometimes, which is a failure with the following error message:
Unknown error (Details: Function "_rtContextLaunch2D" caught exception: Assertion failed: "static_cast<size_t>( recordIndex ) < m_sbt->size()", file: <internal>, line: 1476)
Both of these errors arise from running the same code without any modifications to the input. Unfortunately, I can’t find anything deterministic about this or whether the two errors are related.
