I've been a Redshift user for as long as they've been around, but after the company was bought they discontinued their student discount program, which means I can't recommend it to students or use it in classes I teach, so Karma has arrived at the perfect time.

So I was wondering if there were any known ideal settings for exporting textures from 3D Coat for use with Karma? I tried using the generic “PBR metalness” setting in 3D Coat's exporter, but when plugging the textures into the Principled shader I am not getting the results I am expecting. Specifically with reflections, specularity and metalness.

I'm wondering if 3D Coat's terminology is different than what Houdini uses, so I'm simply either exporting the wrong textures or specifying the wrong texture because 3D Coat's metalness is not the same as Houdini's.

Thanks!

The principled shader is pretty standard. PBR metalness really only means one thing. Perhaps there is a gamma issue? Are the textures exported as linear exr?
