Rigid body cubes exploding when on floor So I followed Andrew Price's tutorial on making a realistic floor using bump maps, displacement maps, etc. I did it, everything turned out great, until I actually played my animation.
My cubes that were sitting happily on the floor violently exploded. I realized that I had to move the cube quite a bit above the plane so it would sit nicely on it without exploding.

Here's all the nodes and stuff



Is there a way I can get the cubes to sit on the floor without exploding?
Looks pretty weird just floating in the air like that.
One easy solution is to add another plane which will be use only for collisions.


Turn off the rigid body on the floor you have now.
Add a new plane, and position it so that it is at (or sightly below) the top of the bumps on your original floor.
Add passive rigid body physics to the new plane.
Disable render of the collision only plane, by unticking the camera icon for it in the Outliner.
