How to use comp nodes in VOPs?

Recommended Posts

I generated some simple images using COPs. Is there a way to use these as textures in VOP context?

I tried using:


for the texture map, but it doesn't seem to work.

Can I do this without rendering the COP results as images to disk?

Thanks :)

you can reference them using op: syntax like


or in your case


EDIT: but be sure you are doing this on VOP parameters not inside of VOP network

Thanks anim. What do you mean on VOP parameters? Do you mean promoted parameters? I tried to use them directly on the parameters of VOPs, but of course it didn't work and mantra complained about not finding the map.

Hi, I've followed this method before, but for some weird reason, it doesn't seem to be working (H15.347).. or I may have just missed something really simple. ^_^

  1. I have a grid, with uv texture:
  2. In SHOPs, I created a simple Material Shader Builder network, the Texture VOP's Map is the only parameter exposed.
  3. Also in SHOPs, I created a COP network.
  4. I then set the shader's texture map to point to the COP using:
  5. Inside COPs, I have a simple File COP set to load the default Mandril.pic
  6. I assigned the material to the Grid object then lastly, I rendered the scene.

  7. But if try and directly reference the Mandril image like so:
  8. It renders fine..

What could I be missing?
