Vop Parameter To Sops

[brandonY]

i made a custom displacement shader, and i have a red channel parameter exported out, but i can't figure out how to get access to in inside the point sop. im not sure what expression i need to use.

Not quite understanding your question buuuut, are you using $CR?

i just want to be able to emit particles from a channel on a texture.

I've attached an easier way. To answer your original question, I think you can just use the point() expression provided that you properly exported the parameter as an attribute.

thanks edward, i will give it a shot.

let me see if i can explain a bit clearer i have a shader that has an animated mask which reveals the texture and there for driving the emission of the particles. i was thinking i might just have to make a custom VEX SOP to actually get the values for the emission. i wasnt sure though.

thanks for the help so far!
