I need to set an object not to self occlude. According to the docs, this can be done with the "Id_nonself" feature, but I cannot figure out how to use it.

id_nonself works similar to id_inclexcl in that it is an object instance label determining which objects do not self- occlude. Set to 0 it has no effect. Set to a positive integer will prevent any object with that label from occluding other objects with the same label.

Nevermind. I found the answer on another site.

1) Select the object and object the transform node in the Attribute editor.

2) Add an attribute.
name: “miLabel” (Yes, it’s case sensitive)
type: Integer
default value: any positive integer

3) Assign a mib_amb_occlusion shader to your objects

4) Set the Id_nonself value to be the same integer as your mislabel
