Smoke density based on ramp

Recommended Posts

Hi everybody,

I am new to houdini and i am already scared.

I know how to emit pyro from colors by using ramp than a delete node with a $CR < 0.1/.5/.8. on my emitter

it work but i want to control the "density" of the emission based on the gray level of my ramp/paint node. Meaning white zone = 100% emission dark zone = 0%

thanks you

I don't really understand what you want to achieve, but why don't you multiply the density by the color of your emission zone ? And then you can remultiply it with a constant after to control the amount of density, if you want more or less.
