Hi vedic

here is the link to the CGTalk forum where they were discussing how to use the Parti_Volume shader.

look about half way down the page for a Name called Digidim
he gives a brief description of what to do and also has a test scene to try out.

If you have any trouble give me a shout and ill see if i can help.

now, back to work for the weekend :attn:
