I'm using the Mesher Compound object on a particle system SuperSpray object. The Mesher Compound useful when you want to use geometry based modifiers or a Corona displacement modifier on a particle system since you can't do this directly on any particle object.
Rendering works fine until geometry motion blur is enabled - in this case, Corona will hang while parsing the scene and eventually crash to desktop. Unfortunately no minidump is created.
I tested Mesher with standard animated geometry and it works fine. It looks like it's happening on particle systems only.
Is there anything that can be done about it?
Attaching a scene - Max 2020, Corona v5
To repro:
- open the scene, the layer '01_Mesher_Standard_Geometry' is visible
- render
>>> all works, motion blur works on the sphere with animated noise and the mesher object
- unhide the layer '02_Mesher_Particle_Object'
- render
>>> Corona will hang/freeze and eventually crash to desktop.
Note that if you disable motion blur in the camera it works fine.
The offending object is colored red in the viewport ;)
Additional note - it looks like the particle spray is causing problems and leads to crashes even if no mesher object is visible. If you make the motion blur to last longer - 1s for example - Max will eventually crash when scrubbing the timeline and forcing it to update while in IR. This time it crashes with the CER dialog. Attaching the minidump from that crash, too.
