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?
in the material_config for the loot asset, look at the render_template.
there's something that say contour or some word, that tells the game to gave contour to them
note that I've never deal with asset that have this, but thats usually how contour is done
