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"

Difficulty detecting collision between motion controller mesh and small physics object.

I have a mesh attached to my motion controller in the player pawn, and I am trying to knock around a physics object with it.

This works fine if I'm slow and intentional about my motions, but if I move quickly it will go through the physics object without detecting any collision.

I have CCD turned on, but this is the only thing I know to do to improve the issue. I'm not sure if there is another way that collision detection can be improved in these situations, or if this is a problem unique to working with motion controllers (maybe the updates are just snapping the controller mesh to various new locations without providing interpolation data for CCD?).

I'm looking for solutions that I could try without using C++.

Have you found a solution to this? I'm contemplating ray cast to my previous frames location.

I think instead of attaching that mesh to the motion controller you need to do set location every tick to the position and rotation of the motion controller with sweep on. But your mesh will then lag behind because of the low latency of the motion controller. So the best might be to make the visual mesh attached and the collision of the mesh separate with set location.

i've got the same issue with current UE versions.

I'm having a similar issue in 4.16 that I believe are caused by the same thing. Did anyone ever find a solution to this? I have CCD enabled and substepping enabled as well.
