Hi, I upgraded to UE4.8 recently and I have this really odd bug. I made an actor, which consists of a physics asset (rope), in the construction script of this actor, I attach collision capsules to the different bones, attach them to the bones and set collision response to all channels to Overlap. This worked fine in 4.7, but now even if I set the response to overlap or ignore, the capsules always block my character from moving through them… And the really strange thing is that in my 2nd level, where I use this actor I dont have these problems. It just happens in one level. Is this a known issue? ---

I am having similar problems with Skeletal Mesh Physics Body collision in 4.8. I had no problems in 4.7, but now it seems that collision only registers less than half the time. ---

Hi dj\_joey, Can you send me a stripped down project that displays this behavior along with instructions of how to reproduce it? I’ll be happy to take a look. ---

Ok I’ll do that tomorrow. How can I send you the project? ---

If you load it to a . you can upload the . here. If the file is too large upload it to a trusted FTP service such as dropbox and you can either post the link here or, if privacy is a concern you can private message me the link on the forums (same username) and I’ll pull the information from there. ---

Hey . I had some time while watching the EA press conf to strip down my project. I’ve sent you the project per pn. I hope this helps. Tell me if you need something else. ---

Hi dj\_joey, I was able to reproduce this and have entered a bug report, UE-17121 to be assessed by the development staff. It appears that the PhysicsBody collision channel can be set to overlap to workaround this error for now. ---

Hey , did you also notice in the project that the overlap and endoverlap events are triggering too often? I mean not just once when entering / leaving the capsule. Is this another bug / the same bug or is this by design? I don’t see this behaviour in 4.7. ---

Hi dj\_joey, There is a known issue with physics objects and multiple overlaps, listed as UE-12386 in our system.
