VDB Opacity Ramp

Recommended Posts

Hey guys,

 

I am relatively new to Houdini and I was hoping someone here could help me with a problem that I can´t solve on my own. I have particles that I convert to VDB. I would really love the density to decrease with the particle´s age. It is supposed to gradually dissolve and not just disappear when the particle dies. I have tried many different things but I cant get any results. This really does not sound like something that should be very difficult so hopefully you guys can help me with this.

Thank you!
