Hello, my goal is to have instance static meshes stop moving once they have collided with a static object. My findings are that moving ISM’s have no collision with any objects that aren’t moving in any way. I was wondering if there is a solution to this, or this is an intended feature and I should change my goal.

Instanced static meshes and collision

Hi Whammy, I’m using HISM and ISM actors in my current project and havent had any issues with collision at all. You mentioned that the mesh being instanced already has collision - what about the actor that holds the ISM? Did you check the collision setting on the actor spawning the ISM? Things to check: Drag the actual mesh to your level and check collision first (not instanced, just the actual mesh to your scene) Change the mesh on your ISM actor and see if something as simple as a cube ha…

Similar yes, but not exact. The ISM’s in those particular questions were static, while mine are mobile.

That’s fine, thanks for responding anyways! After a week of this dilemma, I think that this feature was intentional, to save on performance. I’ll develop a workaround.
