OptiX v3.0 Exception "Unknown, [6619200]"

Hi,

I have been pushing OptiX a bit with a latest bit of code but it falls over at a difficult to track time. All I get is a GPU deadlock and an exception:

Function “_rtContextLaunch2D” caught exception: Encountered a CUDA error: Kernel launch returned (999): Unknown, [6619200]

Any ideas of a cause? I would assume it may be related to adding/removing entities from a group too much or the likes but not sure if there is a trigger/setting that throws it out!

Cheers,
Craig

It looks like it is a generic kernel launch error. So either it is happening with the computation of AABBs or the actual launch, but that probably doesn’t help much.
