Is it possible to emit particles where the white part of testure?
In maya, we can emit particles from texture. If I make a dynamic texture, I can emit from dark or white.
Can somedoby help me?

You sure can,
I normally use a pic expression to get colour data onto the primitives you emit your particles from, and then reorder the primitives (or points) to get the emission based on a certain axis. You can either use the colour attribute for emission or just delete the parts that don't get used for emission according to a certain threshold, merging them back together after the popnet.
Hope this helps

Hi,
Here's a video tutorial [sidefx.com] that should help you.
Also, please search through the forum with these keywords: “particle AND color” or “particle AND texture” and check “Search for all terms”. You should get quite a number of posts regarding this topic.
Cheers!

Hi there is anotehr way of doing this. I attached a file. I use a vopsop to generate a attribute onto scattered points that I can later use in a delete sop. this is quite fast and I can use this points as source for my particles.
have a look it it works for You .
