Thanks

Hi,

 

in vops, drop a "bind" node, set the attribute name to "uv" (I hope u have uvs on the geometry), change from "float" to "vector". Then, conect the output of the bind node to the "vector to float" node, and the first 2 outputs of the last node, in the "s" and "t" inputs of the "texture" node. The color output of the texture you can conect to the color output of the vop.

 

Now you can use the "$CR", "$CG", "$CB" expressions to get the rgb values of the texture.

 

Try this and if you get stuck, I will drop a hip file later.

This should do the trick for you :3 Replace the sequence in the VopSop with your own. Cheers

First of all you need to bring that animated texture color to source geometry point using "colormap" in "vopsop". Then group points based on color. Then use that group in source group parameter of "POPSorce". That's all.

You can also use "AttribWrangle" to keep emitter points (colored )only. This way you need not use group in "POPSource".

if (@Cd.x < random(@ptnum+1000*@Frame)) 
{ 
    removepoint(0, @ptnum); 
}
