Pyro - colour smoke by age


Recommended Posts

I've no idea on the thread, but I've done a lot of this.

You can do it in the smoke sim, but I've found that if you advect particles through the sim and create a field from the particles you end up with a better result, and a more directable one at that as you have more control over blending radius etc post sim.


So do your sim... You could advect particles through it then, or after you've cached it out.

Create your colour attribute on the points based on age however you want.

Create a new vector field called colour that is the same size and res as your sim (or downres if you prefer).

Use the VolumeFromAttribute SOP to copy the Cd attribute accross to the colour field.



Hope that helps
