render wetmap

Phoenix General
1

Hi there,

I’am try’n to simulate an effect like tint wich sinks into paper and expands in it.
I’ve try’d to use wetmap with consumed liquid, but without too much luck.. (is there a way to render wetmap only?)
or is there another way to go?

thanks in advance for any tips and hints on it. :slight_smile:

best regards

Jonas

the wetmap is rendered via the particle texture, an old phoenix undervalued tool

i see. thanks. how would i animate the wetmap though? like expansion over time. when i animate the blend radius it expands uniformly.

any hints by chance?

what you are trying to achieve?

smt like this.
like a pen in CloseUp writing, while the ink expands like in the link below.

you can use a setup like in the attached file, a simple gradient is used as “wetmap”, replace it with the real wetmap
