UDK - Collision Not Applying to Mesh

dwgagner

So every other object I apply to collision works, yet I have a simple floor tile that is essentially a box and when I try to apply collision to it nothing happens. I mean it updates and no longer says that the mesh has no collision but it doesn't actually apply any collision. Using show collision in the editor shows 0 collision lines.

Things I have checked just through generally trouble shooting:
Normal Directions are pointing the right way.
I checked scaler info in max and performed a reset xform anyway.
I duplicated a new one in max and re-imported.
I tried building my own custom collision and saved out a box with the mesh called Tile and UCX_Tile, it gave me a message recognizing collision info but didn't actually apply the collision.

This is totally ridiculous because it's literally just a subdivided box with a lip.

How thick is the collision mesh? I've had this problem for meshes that were considerably thin. Try making the collision mesh thicker. Otherwise, the model will say it has a collision mesh, but no primitives are detected because they don't meet Unreal's minimum threshold.

k so that fixed it as far as collision but now when I walk on it I bounce for some reason.

Hmm. That normally happens when you're standing on a rigid body and the game is trying to get you off of it. Is your floor set in as a static mesh? What's your collision settings look like?

Make sure the scale isn't super big or small as that also makes you bounce. Import the mesh roughly the size it should be rather than scaling it hugely in the editor in case you are doing that.
