Cool - that’s interesting news, and PBR is always a juicy option for ppl working on ambitious projects. Btw - I found your documentation really useful to understand everything. I finally properly understand how it all works.
I hear ya - I have little free time too. If I find time, I have my sights set on an anime-hair-specular shader (a particular hair shading style that’s like using a dodge-brush on highlights).
Eventually XD … In the mean time I gotta shovel and fix stuff. Fun fun. ;p
