hello,

I was wondering, is it possible to use an animated greyscale image as a particle emitter (and im not talking about the operator button under the shape menu)

Its because i like creating emitters with particle flow in max, but i want to use combustion to actually render the final effect out.

cheers for any help.

Do you mean emit based on luminance like PFlow? No. Just line, dot and area.

Is there a way to map movies to particles rendered in PFlow? Yes. Render out a UVW pass, and then use the Gbuffer builder and 3D Texture tool, then apply your Combustion layer to the UVW coordinates of the particles (if you rendered them using planes/facing planes/spheres/etc geometry).

hey thatoneguy, thanks for the advice.

"Yes. Render out a UVW pass, and then use the Gbuffer builder and 3D Texture tool, then apply your Combustion layer to the UVW coordinates of the particles (if you rendered them using planes/facing planes/spheres/etc geometry)."

- sorry but im really new to using combustion. i dont really understand, do you think you could spell it out to me through the steps?

thanks again.

If you have 3D studio max, render out the particles with geometry for the shape.

Here is a pretty decent tutorial on exporting RPFs.

and here's a pretty quick explanation of how to do the rest in combustion:

Sorry I dont' have time, or combustion in front of me. I won't be on my workstation until Monday. If you still haven't figured it out by then I'll be happy to do a step by step for you.

To get the effect you want you would need the Particle Illusion 3 engine. Combustion only has the Particle Illusion 2 engine. You could buy PI3 and use that to do the effect in the same way you would work with Combustion particles, but with alot more advanced features. I hope that at some point we will see an update to the Combustion particles, but I have no idea if it will ever happen.
