Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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 the component's Rotation (world or relative) will crash the 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, the next attempt to set rotation will crash. Unless you haven't got CCD on for the component. But then maybe your thing falls through the floor.

Hi Filoppi,

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?
