APEX cloth collision with wall

Hi guys does anyone know where i can find a tutorial which shows how to make APEX cloth collide with a wall. All i found were the ones which makes it collide with the character. For my scenario it’s a bit different as the wall is not part of the cloth in the max file as I am placing/ need to the APEX banners all around a stadium which I’ve modelled so having the wall as part of the model is kind of hard/ impossible.
