Object Collision for Moving Actors in Matinee?

I have two actors set up to move back and forth in matinee, acting as an obstacle. However I cant get any of the settings to block the player pawn, which is the PhysicsBall in this instance. I’ve tried BlockAll etc but none of them seem to be working. Any ideas? Thanks in advance.

This may not work fully, and it appears to still have some collision issues (or at least clipping issues in my case, depending on how you hit the object), but this mostly did the job for me.

In the static mesh panel (double-click on the thumbnail of your mesh) under Static Mesh Settings > Collision Complexity, I have it set to “Use Complex Collision As Simple”. I don’t think your collision type matters but I haven’t tested other types yet.

At the main screen, under Details > Collision (with my mesh selected), near the bottom (below the line break), I checked the box for “Trace Complex on Move”.

My character can still clip into the mesh if I hit it the right way and get briefly stuck in it, but it otherwise seems to be functioning as intended. Hopefully this helps you if you haven’t already found a solution.

Add blocking volume around your mesh which you want to be player pushed by. Attach this volume to mesh which you animate via matinee.
In character BP, in capsule component, set trace complex on move to true.
Then player will be moved by blocking volume.
I tested it on 4.6 and it works.
