I opened a brand new file, and made simple objects where I applied textures provided by the add-on Extreme PBR Evo. All of the objects are now rendering as semi-transparent. And I have no idea what changed. Again, it’s a new file. I even tried other materials which wouldn’t necessarily be transparent (metal, etc.). Not sure if it’s a bug in the add-on, or some setting I accidentally flipped on.
I’ve included a link to the packaged file.
Any help would be appreciated!
