How to create collision information for procedural geometry?

Have a look at UModelComponent, that should be a good model to follow. You want to implement IInterface_CollisionDataProvider and the GetPhysicsTriMeshData, ContainsPhysicsTriMeshData and WantsNegXTriMesh functions. Then you add your own UBodySetup pointer to the component class, and create when needed. Make sure when you allocate the BodySetup that you set its Outer to be your new Component class. The BodySetup will see if its Outer implements that interface when creating collision geometry.

Edit: I’m not quite sure from your post if this affects what you are trying to do, but I’m afraid we do not support cooking collision geometry at runtime.

I have reimplemented the CustomMeshComponent example class (renamed GeneratedMeshComponent) and integrated the elements you mention. However, the generated mesh still does not provide collisions. Maybe I am doing something wrong. For example, since it is a generated mesh, every time I set the triangles, I regenerate the UBody (instead of checking if it is NULL). I do not do it in PostLoad. I did SetActorEnableCollision(true) in the parent actor.

Here is the code: http://www.base64.com/GeneratedMeshComponent.7z

Can you look at it and tell me if I am missing something?
