billowing Smoke..

Try putting your particle age texture in the opacity swatch. That way the particles will become transparent when they reach color #3.

Can't advise something better, always listen to the JED, that however should sign his real name Dundee :p

I tried that but it doesn't seem to work!

I did the tutorial on http://www.maxhelp.com/content/tutorials/billow/billow.htm but it only seems cool when using a black background..since the color#3 is black!
However the tutorial uses "particle age" in the diffuse slot, and the gradient in the opasity slot!If I swap the 2s, it doesn't really seem to work??

Thanks for your help

recipe for particles:

particle system should be 'facing' type....

in mat. editor under 'shader basic parameters' click face map and 2-sided

specular level = 0
glossiness = 0
soften = 0

"maps"

opacity map needs to be a gradient....change from linear to radial and make sure the white part (visible area) is on the inside ....

after that u should be ok, go ahead and apply a bitmap or just change the diffuse color...i hope i explained it properly

attached is a (compressed) pic of an animation i'm working on at work right now where i used this method....it's not finished but....oh yea and the red #'s are frames
