SgtSpamBoy Posted May 4, 2007 Share Posted May 4, 2007 Hey everyone! (this is my first post, yay). Using particles with metas/spheres/sprites, I know how to colorize and control alpha based on the life of the particles using $LIFE or $AGE - this time I am using i3d to make a thick smoke trail from a missile. Is there a way to colorize or apply opacity to the smoke based on its age/life? As far as I know, the POP/particle info is lost once it's converted to i3d... What I'm wanting to do is have the smoke gradually dissipate by becoming more transparent over time, but not universally. Actually I just thought of a possible solution - using a ramp for the density on the texfog shader may do the trick. The ramp may work in theory, but I don't know how to implement it at this time. Any thoughts? Quote Link to comment Share on other sites More sharing options...
doc Posted May 7, 2007 Share Posted May 7, 2007 Welcome to the forum, have a look at this post it should point you in the right direction: http://forums.odforce.net/index.php?showto...3235&hl=i3d I'm pretty sure that someone has already posted an i3d shader that writes out color (and a coresponding fog shader that reads it) If you search the forum you should be able to find it.
