Crash: CCD + Disabling Simulate Physics, then changing Rotation

If CCD is enabled on a StaticMeshComponent in a class Blueprint, turning Simulate Physics on, then off, then attempting to modify component’s Rotation (world or relative) will crash editor. This is pretty reproducible for me.

Example scenario: you have an actor with behaviours that involve changing a component’s rotation, but you want it to simulate physics briefly (say, fall to ground) and then disable physics again and resume normal behaviour. Once simulate physics has been disabled and re-enabled, next attempt to set rotation will crash. Unless you haven’t got CCD on for component. But then maybe your thing falls through floor.

Hey ,

Please and attach crash log and dump file for your project after this crash. You can read more about where to find that information here:


Hi ,

We have not heard from you in quite some time. I am marking this as answered for tracking purposes. If you are still experiencing this error, please respond with requested information.

I have same problem. nothing more is needed other than his description.

Hi ,

Unfortunately this crash could potentially be caused by several factors. Can you upload your logs, callstack, and dump file here so I can take a look?
