Hi. The task: to divide the interaction of solid objects.
Explanation: There are 2 layers. On the first layer the red brick should interact with the red wall. On the second layer blue box should interact with the blue wall. How to make it? I turn on the wall solid attribute and boxes collides with both walls. I need to divide solids in layers that the red brick collided with only the red wall and the blue box with only the blue wall.
