I’ve been replacing materials to consolidate them in my model. I use Vray to “Select Objects in Scene” (with that material) then select the new material, and then “Apply to Selection” which does a great job of a find/replace function. I then “Purge Unused” in the SU Material Editor.
90% of the time this works great.
The other 10% of the time the replaced material is “stuck” in my model and I can’t seem to purge it (I can of course delete it, but then I’m concerned it’s going to be a problem somewhere else if it’s still clearly attached to something).
I’m guessing that if there is a component in the model that once used that material originally that the material is forever bound to my project so long as the component is there. Am I right or is there a better approach?
