The way I would approach this would be to animate, rather than to use physics .
... and I would build a series of groups with the die at the heart of this
hierarchy.
The outer group would animate the path of the die
The next layer would animate the Rotation in X
The next layer would animate the Rotation in Y
The next layer would animate the randomness
the inner most layer would be the die (this also allows you to substitute in
another die without rework.
Then I would composite the result into the final image and that is another
story.
Breaking things down into simple parts, and isolating the animation from the
object go a long ways to retaining sanity.
Hope this makes sense and is of help.
Yours,
David

Subject: [Carrara] Rolling A Die
I've tried a variety of solutions for rolling a die on a table. I
want it to travel in the Y, bouncing on a table until it stops.
I've tried directional forces. I've tried spin modifiers. I can't
seem to figure out how to get the die to spin realistically and
interact with the table.
With directional forces for gravity the dang thing always ends up
floating around in funny ways.
So:
Issue 1) How do I get the die to spin realistically (multiple axes)
as if spun off of a hand.
Issue 2) How to have it then bounce realistically off the table (one
or two times).
Issue 3) How to realistically portray gravity.
Oddly enough, getting the die to land on the number I want will be
the easy part!
