Smoke changing color

Recommended Posts

Hello!

 

I am new to Houdini, but am attempting a fairly complex effect. I need to emit smoke and particles from a piece of geometry, with these specific characteristics:

  • The smoke and the particles must start off as grey.
  • The particles should be emmited from a black-and-white mask that is mapped onto the emmiting surface (white=emit, black=no particles emmited). This texture should be animated.
  • The color of the particles should be defined at particle birth by another moving texture (an animated fractal noise, for example).
  • At 1/3 of their lifespan, the smoke and the particles would change into two different colors (blue and pink,.

I am guessing that the right way to do this is to start with the particles, and then copy the color attributes onto the smoke. The two should move together, so... should I first do the smoke, and them move the particles along the same forces? 

Any help would be greatly appreciated!

cheers, 

 

Diego
