Hi!
I'm interested in using the old BRDFs, AiWardBRDF in particular. Unfortunately the only example I found anywhere was https://docs.arnoldrenderer.com/display/ARP/Implementing+MIS-sampled+BRDFs
Google and a GitHub code search resulted in exactly nothing, so the mentioned link is the only point of reference I have. PhongBrdf however is not shown there and I assume that for Ward, the examples would have to be modified anyway?
Any help would be appreciated!
