Is there a documented limit to the number of instances Houdini Engine for Unity supports? I'm trying to bring in between 10K to 100K instances of a prop and I seem to almost always succeed at less than 10K and almost always fail with more than 50K.

I'm on a machine that should handle it, 64GB RAM and RTX2080. It doesn't seem to matter if the material on the prefabs is marked as GPU instanced or not.

Unity hard crashes, and the Windows event log indicates that the DLL that got the segfault was Mono.

Anybody have any recommendations? Is this just not supported to instance so many prefabs at the same time?


P.S. The prefab is a cube
