Cloth Collision doesn't interact with environment

Hey,
I’ve been trying to make my cloth collide with the environment but it doesn’t happen. I enable Collide with environment and made the white block it’s hitting “Block All” but it still doesn’t work. I’ve tried exporting out this model from Maya with just simple parenting and giving the pole and cloth it’s on material but I don’t know if it’s an export issue or I’m missing something in UE4
