I need a number of shading properties that are unique per object, so I can control the strength of a couple of effects in the shader. The color property in the Object info node is a perfect example of what I'm looking for, but I need a few more properties than just the color.
Is there any way to access custom properties, or something equivalent, in a similar manner? And preferably in a way so that objects that don't have that custom property added don't break the shader?
