Particle density? 2004-04-26 - By Nicolas Petit
Back
I was wondering if anyone might be able to enlighten me on how the
particle_scalar node, set to density actually works... I've searched hi and
low and fiddled around with it, but the more I play with it and the more it
seems I don't understand it...
After normalizing its output and inverting it, I get virtually the same
results. I was kinda hoping to make the areas which are particle rich more
transparent unfortunately, no matter what I do, plugging it into a scalar
urinary set to invert, plugging it into a gradient mixer node, change range,
division etc, nothing seems to get me to the results I'm after... same with
trying to get a sharp falloff on them either... (this is after normalizing
them as well as when leaving them at their default value)
So, in short, does anyone know what the value range that is being output
from them and how it's calculated? Does the size of my scene have anything
to do with it?
I'm kind of getting some results, but it's very hacky and I'd much rather
have the actual particle density drive their transparency to some degree...
Cheers!
Nick.
