I have several objects that share the same material.
This material has a mix shader node, whose the FAC parameter should be linked to a custom property of the object having that material assigned.
From what I read, I need drivers here, so I've set up one (see screenshot).
But I need to set an object as input for the driver. I don't want to select each object manually. What I would like is that the driver refers automatically to the current object.
Is it possible, or do you know a better way to achieve this ? Thanks.
