Outlines on Loot. Need to disable it

Since when were there outlines on safe and bank heist loot?

I figured out that its the main problem affecting my mod and is the reason for the crashes. Unfortunately, I have no idea how to configure my custom models to accommodate these new contours. Is there anyway to disable it?
You could be able to try removing the contours by copying the mat_config file to the respective folder in your mod's folder and forcing the game to load them via the add.xml. But don't forget to remove the "CONTOUR" tag from the mat_config.
