I'd love to auto-detect and load texture files when creating materials. I often have a subfolder with 4 files: diffuse, specular, roughness, and normal- and they're named with a pattern. Is there a way to have the cop file node automatically detect the (*_roughness.png) file if I tell it the directory to look in?

In a perfect world, I'd love to make an HDA with an exposed folder location: I tell it the subfolder, it makes a material out of the png maps inside. Is this possible? Thanks!
