Animate pScale of flip overtime?

[bifrost]

Hey guys! Was wondering if anyone has an idea how to decrease the pScale of flip fluid overtime during the sim?
I am trying to do a shrinking effect using flip and thought this might be a good place to begin with.

Unfortunately, animating particle radius scale on the flip object doesn't really work.

If you have any other idea how to achieve the shrinking effect, please let me know.

All help is appreciated.

Cheers,
b

Try a geometry wrangle connected to the 2nd input in the flip solver

f@pscale *= 0.99;

Thanks a lot John! That works like a charm. Can you explain the logic here please?

*= is a shorter way of saying  @pscale = @pscale * 0.99;

The wrangle evaluates at every timestep, so each time it does, it makes pscale be only 99% of what it was on the previous time step. That will make it get closer and closer to zero.

I didn't know it did the calculation every timestep. It makes sense now. Cheers James!
