So I’ve hit a wall on this and thought I’d put it out here for any thoughts.
I have a character that I need to emit particles from different specific areas of his (single mesh) body.
I knew that you can drive particle emission rates with textures.
So, I painted a bunch of textures for the emission areas and connected them all with a bunch of math nodes to mix and blend the different maps as needed.
But, when I plugged the final image into the texture rate on the emitter...it didn’t work.
I spent a chunk of time checking all my connections and math...and while it creates a wonderfully controllable color map, it is useless for driving the emission rates.
Now I’m here just frustrated at something that really should work.
As things stand now I plan to just create a separate emitter for each texture...which is fine.
But maybe someone can shed some light on why this doesn’t work.
and/or give me some thoughts on a way that I could use an advanced animated procedural color map to drive particle emission rates.
I’ve attached a very simple example scene to give you a basic idea of what I’m trying to do.
I’m assuming that if I get something like this working I should be able to scale it up to meet my production needs.
But such assumptions got me here in the first place. :)
Thanks for your help!

hi there,
well i dnt know the technical problem behind this but i can give you a very simple solution,all you need to do is bake the texture applied to the geometry and plug the resulting file texture on the emitter.i have done the same thing on your scene file you can have a look.i hope it might help to solve your problem.
attaching the scene file.
cheers,
Karan.

Karan,
Thanks so much for the response.
This was the first thing we tried...and while successful for the simpler scenes, we were hoping for a bit more interative control.
We’ve got 10 shots we need to use this setup for, so the hope was to have a robust and interactive setup.
When my lead says “lets have the hand emit two more frames before the shoulder” I would love to just move the key frames on the texture control and play it back and tweak as needed.
But again, thanks for taking the time to help me out...it actually means a lot to get confirmation that baking may be the only way to go.
All the best.
