Hey Chosker,
Thanks for submitting this. I had a hunch about what was causing this and I was right. The collision mesh is not updating on animations inherited using “Set Master Pose Component”. This seems to apply to both per-poly and physics asset collision. So this is not isolated to traces.
I’ve entered UE-27081 to have this issue resolved.
I do have a temporary workaround for you that can work in the interim. Use one physics asset that provides collision for the entire body and apply it to the Master Component, then disable collision on the slave component. I realize that’s not a great fix if you plan on selectively adding armor, clothes, etc. It should help you get some of the results you’re looking for now.
Note: Just realized my workaround doesn’t work great for your situation with per-poly collision, but if anybody else runs into this issue using physics assets, this is possible workaround
