Apex cloth not collide with floor(ground) It goes right through

apex cloth not collide with floor(ground)
I have it colliding with my rig and I can get it to move right but it goes through the ground. I have tried to even create a floor mesh and it still goes through. In maya it doesnt go through but in unreal engine 4 it does.

Please let me know or point me to direction.

here is a picture of the issue

i am using unreal engine 4.1

As far as I know currently there is no perfect solution for this issue since UE4 or APEX ( but I think it is UE4 ) does not support the complete interaction out of blue. so you have to add physic objects to your cloth. for this in the app you design your cloth you need to make bones for your cloth and then in unreal attach the physical boxes to the joint of the skeleton of the cloth. even the result of this won’t be nice. however for self collision try using maya and nvidia apex tool in maya for making character cloth there you can make collision with a character.
the problem is that UE4 does not support softbody. if they had it would have been much easier to implement
