Houdini 21.0 Copernicus

Filter List

The Filter List window lets you quickly apply effects in your scene.

Overview

A Filter List is a list of COP nodes that let you quickly apply effects in your scene without having to set up an entire COP network. Edit and rearrange nodes directly in the Filter List window. Houdini applies the nodes in the order they're listed.

Note

  • Though some nodes available in the window include multiple inputs and outputs, the layer passes through only the first main inputs and outputs.

  • Though you don’t need to navigate to a slap comp network to change the nodes, a slap comp network is created in img.

Using Filter Lists in slap comp

  1. Go to the Solaris viewport (/stage).

  2. Set up a slap comp network in the Solaris viewport.

  3. the Control Slap Comp settings button and choose New Filter List. This opens the Filter List window.

  4. Click Add Filter and choose from the list of nodes to apply them to your scene. You can set and reorder these nodes directly in the Filter List window.

    You can now the Control Slap Comp settings button and choose Edit Current Filter List to further configure the Filter List.

Using Filter Lists with the USD Render ROP

  1. Go to the Solaris viewport (/stage).

  2. the Control Slap Comp settings button and choose New Filter List. This opens the Filter List window.

  3. Click Add Filter and choose from the list of nodes to apply them to your scene. You can set and reorder these nodes directly in the Filter List window.

    Note

    These changes won’t apply to your scene until you reference it in a USD Render ROP LOP.

  4. Create a USD Render ROP LOP.

  5. Go to Husk ▸ Slap Comp.

  6. Add a Slap Comp and set its Source to COP Filter List.

  7. Set COP Filter List to the location of your COP Image Filter List node (for example, /img/copnet_filterlist1).

    Karma now applies the Filter List. the Control Slap Comp settings button and choose Edit Current Filter List to further configure the Filter List.
