I guess the title says it all.
But lets say I have a material named M_MetalGold in my scene. Then I drag a model from the AssetBrowser that has a material also named M_MetalGold. The default behaviour is for the material on the model to become M_MetalGold.001.
Instead of replacing all the materials with existing ones, then clearing orphan data etcetc every time I append an asset, I would like for the slots with the same name as existing materials to be automatically overridden.
Does anyone know for a solution for this? Is there a script or add-on that does this? I havent been able to find anything so far.
Glad it worked for you, and thanks for the reminder! I had forgotten about this great add-on because it’s been awhile since I’ve done any mass appending of files…
Thank you so much for the addon! Its a life saver. Indispensable for building an asset library for me. I dont use a lot of unique textures - just a lot of reusing the same tilable wood/ metal/ fabric materials. This way I can assign the materials and save the asset like that and then run the script every once in a while to clean up when I use it in a project.
Worked really well in 3.0 ( didnt test in 3.1 yet ). Just needed to be copied directly in the addon folder (not nested in its own folder). I suspect it has something to do with the naming of that folder but who knows.
Thanks for the kind words, but I don’t have the programming knowledge to make any add-ons. @vitorbalbio and @brickmack deserve all the credit for this gem! Glad it’s still working in Blender 3.
didnt go back to the original post to see whos who haha. My bad! 
Yup! Thank you
