Bake Particle Path into texture?

#1

I did a search but didn’t find anything, if I’m missing an existing thread my apologies.

I have to sort out the right way to do an effect. I have rain drops hitting the top of an umbrella, then going down the surface and dripping off. What I want to do is have an animated trail behind them to use as a mask to drive a blend material so I can make the surface wet. I’d like it to be animated, so it ‘dries’ after a second or two.

I came across a great little plugin called "particle paint’ by Peter Watje, and it seems to do everything I need except blend the trails together. So I get something like this rather then a blended frames version. (This is a simple example, so a directional blur won’t work on the real thing)

So my question is this: Is there a better way? How can I blend these dots together on bake? Or… maybe with after effects?

Thank you for any help you can give.

Hey diffus3d, have you tried increasing the integration steps?
great plugin btw.

I did try to increase them to 1/8th of a frame… maybe I should go even more detailed. I didn’t really notice too much of a difference but the truth is I maybe didn’t look hard enough. I always wondered what the occasion for ticks might look like, I’ll give it a shot. Very cool plugin!

Thanks! :beer:
