Re: RF XSI mixing liquids

["Duncan Burch" <duncan_burch(at)hotmail.com>]

Hey Chris,
Thanks for your reply.
I've got two liquids to mix together into one mesh, using weighmaps as you 
can see here.  Even though the mix works, I guess, not exactly how I wanted. 
The colours dont really ever blend properly, but it is using one mesh, so 
its a step forward.

This next version shows what happens if each liquid has its own mesh, 
obviously the colours aren't ever going to mix, if only they could, would 
look really nice.

Any ideas?
