Just when you thought Doc wasn't looking ... :biggrin:

Quote - Did another experiment. The Volume_StepSize changes when you select different Poser Display Units. So it is in PDU, but the value is not the spacing between the planes. Looks like about 1/4 of the value is used to space the planes. When I put **.**1 PNU or 10.32 inches, and render with a prop of that size, the prop seems to span four fog planes.

Hmmm ........... 0.1 Pnu = ~10 inches
Looks AWFULLY close to 10 DGS inches, n'est pas?  :lol:
Sorry Bags ... couldn't resist.

Remember ... "With Poser, all things are possible, and poseable!"

cheers,

dr geep ... :o]
