how can i access the point color within vops?

i want to use it to shade with it and ad some noise and then clamp it to get a nice sharp and noisy blend.

if you are dealing with vops to build shaders, then have a look inside the basic material. Color is brought in as an attribute called “Cd”, it is a float attribute that should be present on your geometry (as a point attribute).

If you want to use it in regular vop sops, you can use the Global input variable “Cd”.

i can't see it in the global variables. i added a new parameter and called it cd which seemed to work.

That is correct in your shader material you need to create the attribute Cd and assign it a value. You also can manipulate Cd at many other levels like SOPs POPs etc etc. Drop down a VOP SOP and dive inside. Note you can manipulate the incoming Cd attribute and then output it. I often use Cd to view noise that I am creating at the SOP level.
