For some reason, all Cargo materials imported into C4D Redshift (standard material) set the default metalness to 0.8. This causes everything to have a strange metallic look and is the incorrect way of setting up a material. This also removes any transparency from materials as metalness and transparency do not mix.

I know these materials all have metalness texture maps, so I'm not sure why cargo has never applied them in all its updates. I'd love to see that feature added and this odd default metalness setting removed. Manually adding metalness maps seems like a bit of a hassle to do.
