An assortment of OSL shaders for your perusal

Thanks!

Keep in mind that implementing glossy Fresnel properly is not possible with OSL, it must be done in the BRDF implementation itself. You can only get an approximation with OSL.

True! It’s just a blend between the front facing (0 deg) reflection amount and the Fresnel curve, but it holds up surprisingly well.

Great work Rens, stuck in Clarisse land at the minute but gonna have a dig through this in July - osl seems really useful. Also just finished some film shots with Jan Volckmann - he’s great fun to be around and does really subtle comp work.

Hey John! How are things? This should work in Clarisse. Oh nice haha, say hi from me. : )
