Extremely useful. Thanks a lot for making this for everyone to use!
Just looked it over, and it even has TerrainNormal, that's smooth :)
Had lot's of fun watching the bouncy ball forever and ever. Well, until it's always growing momentum med it bounce itself out of existance, dunno where it went. At one point it slid along the ground, painting it with 100+ bounce art effect. But in general, very smooth.
