Setting up a Render Pass
By default, Katana starts with a primary render output (sometimes called the default pass).
The RenderOutputDefine node is used to define render outputs inside Katana. With it, you can set:
• The type of render output (such as color or point cloud (ptc)).
• The output’s file type, colorspace, and location.
• The output’s name.
All the attributes for a render pass are stored at the /root location under the renderSettings.outputs attribute. For instance, the primary pass attributes are stored under renderSettings.outputs.primary.
