Im probably just not understanding exactly what collision detection is...but what im trying to do is create a scene with one object exploding into fragments and those fragments bouncing off the floor...

ive got an infinite plane set up but they pass through it...not even the hint of a bounce...lol...

ive been going through the online manual, but havent found anything...thought id try asking...:)

Hi Todd, Collision detection is really only for use in the assembly room when creating scenes. It allows you to "bump" or put objects in contact with one another without having them intersect. To get the results your asking for will require either the use of phyics or the explosion modifier with the "floor" parameter set to your actual floor. To get bouncing you have in mind, the Explosion modifier won't perform. In that case you'll need to use objects with physics or use a particle generator with "collides with objects in scene" enabled to create that effect. Explosions are actually pretty complex things to create in CG. Mark

yeah i would have to pick the complex thing to want to do..:)..lol..

thanks for the reply...looks like i have lots more to learn...:)
