[Closed] Unusual and Invisible collision on modular pieces
I have some weird collision problem: http://www.youtube.com/watch?v=n5jaS1e2IcQ
As you can see, when there are end-faces on my models, the ball will bounce off like there is a wall. There is absolutely no height difference between the top faces so the ball should usually roll smoothly over the surface.
When there are no end faces on my segments, the ball occasionally behaves like there are some bumps even though there are none at all.
When I use the same pieces as one segment, everything works as expected. But I'd like to work with segments for the sake of better lightmaps. Is there anything I can do?

Thank you for sending us the assets to test, and we were in fact able to reproduce the issue you were experiencing with the assets you provided. What is occurring when the ball jumps between each modular piece is that there are minut float point errors in between each modular piece being "connected." This is currently a limitation of the engine and is not an actual bug with collision.
One suggestion as a work-around would be to use splines to create the shape of the course you would like, and the spline tool will take the modular mesh piece and conform it to that specific path. Another suggestion would be to set the collision on the static mesh within the modeling program a bit offset from it's exact bounds and import that onto the model within UE4. We do appreciate the insight on this matter as it gives us more to improve upon and investigate. Hope this helps!

Thank you for your report. We were not able to investigate this on the engine version you reported, but there have been many version changes to UE4 since this question was first posted. With a new version of the Engine comes new fixes and it is possible that this issue has changed or may no longer occur. Due to timetable of when this issue was first posted, we are marking this post as resolved for tracking purposes.
If you are still experiencing the issue you reported in the current engine version, then please respond to this message with additional information and we will investigate as soon as possible. If you are experiencing a similar, but different issue at this time, please submit a new report for it.
