The “clown pass” is an amazing pass using the Object ID render pass in Octane. It gives you control over selections of each individual object in post by assigning a random color to each object in your “null” or group which is applied an Octane Object Tag and setting the Layer ID to 2. You can see this by placing an object tag on the object, setting the layer id to 2 and activating the Object Layer ID in octane render settings. You can then view this pass in the live viewer by clicking on the OID button in the info section.
