what is "object ID"

[cpz]

Hi, can someone pleas explain , "object ID" and it's purpose, and how to use it,? thank you

Every object has a unique ID

An id is a number like 877055645

So, for example, if you use the object ID color mode in the Utility shader, you get a different color for each object.
