Simulate physics not work and give error

I made BSP cylinder, changed its sides count to 24, gave it material color and created a static mesh from it. I give it complex collision and allow simulate physics but it doesnt move after i stop the game it give error. the cylinder can move if I set it’s collision to complex and simple but then it only drops below the level. How can I fix this can I ?

Hi, the editor can’t simulate meshes with complex collisions. Instead you can open up the static mesh asset window and generate a simple collision. see here: Setting Up Collisions With Static Meshes | Unreal Engine Documentation

I go to read it now, thanks a lot. I knew I was doing something wrong
