My problem is already on title. I tried other Collision Presets but or they don’t collide or they still passing through.
In my game, the shpere will be spawned on the top of a tower and will be rolling in a stair until it touches the character. But, the shpere doesn’t stand in the stair, it… pass through.
First, the stairs need to have proper collision bounds. Second, you need to set the sphere’s collision preset to BlockAllDynamic. If you want it to overlap the character set the collision preset to OverlapOnlyPawn.
Oh, thanks. If you didn’t sayed that stairs need collision bounds, i’ve never found the function to create static mesh. Thanks 
Well, i’m a “little bit” late, but… it didn’t worked. Still passing through. I add collision bounds and selected “BlockAllDynamic” in the stairs, and “OverlapOnlyPawn” in shpere
Try BlockAll instead of BlockAllDynamic for stairs. If it still doesnt work upload a sample project so that i can take a look.
Where do i upload the project?
You can use Dropbox or Google Drive.

Yeah, i’m late, but i still want to know how to resolve this problem
Sorry but 700MB is way too much for me to download. :
You’ll need to create a blank or some other project with no starter content and reproduce the problem, then upload that project.
