What are you talking about? Motion designer?

So is there a particular tutorial you're trying to follow ... or can you describe what you would want to do with the cube and the plane?

I think he has the same problem I have when I've messed about with MD.

I had a cube with a ball inside and I just wanted the ball to bounce around while I rotated the cube, just a simple - first time user to MD test.

No matter what I try the ball just squishes flat and then drops through the cube!

It should be easier than this!!! :(

yeah exactly...

Just in general HOW DO U MAKE HARD BODIES?????

no matter what , they always jiggle...

im not askign anyone to critique what im doing.. just asking how to make hard bodies..

I might be able to describe the problem with the ball falling through the box ... it's all based on the distance between points, and in a basic box, there are only points in the corners, not in the middle where the ball falls through. So (if this is the problem) it's simply a question of divding up the box so it has a finer mesh on the floors and walls. Also "Skin thickness" can have an impact here. Don't forget that surface normals are also part of the equation.

As for doing hard bodies ... I don't know much about it. Because MD is a soft body dynamics engine, the trick would seem to be making soft things as firm as possible.

I'm sure you already know about the "fixed" setting for parts that are rock solid, but I've never tried getting two "fixed" objects to interact.

Maybe if you'd describe what you're trying to do, folks would have a better idea how to help.

Sorry that my answers seem simplistic, I'm not trying not to help, I'm just not sure how.

knew about the point thing, so everything was sub-divided, skin thickness was also up.

the box was also had thickness, so poly normals shouldn't be an issue.

bottom line it just ain't straight forward!

needs the vX treatment me thinks!!! :)

Having issues of my own. Trying to drop a cloth across a Poser figure. I've gotten it to NOT pass through the figure completely, but the cloth and figure always wind up inter-penetrating each other. I know I'll figure it out, but it get's really tedious tweaking and waiting. The SAD part is I have a P4 3ghz machine with 1gig of ram and it's STILL dog slow doing the calcs!

Sounds like you have a very dense mesh :) I guess that would be the poser model. You might want to cut all the bits which are in no way going to collide with your cloth and use that as your collision object, possibly with some point reduction :) It might be a good idea to apply a clip map to your body and fade it in as the cloth covers it... That way you don't see the interpenetrating polys. Not ideal, but it works :)
