Do you need help creating that nifty physics prop? Have problems when it appears to float by a little bit off the ground? Just describe it to me (post on this thread), or better: give me the .blend file.
Features of the service:
Basic breaking objects.
Modeling (if you just give me the description).
Realistic center of mass & density.
Helpful hints (optional):
Be specific. for example, instead of “computer” say “Macintosh computer”
Specify the realism. Do you want a cheap game simulation or something for rendering. (or in between).
Specify the scale. It is a pain to scale most objects due to the collision margin.
