A really good talk by Vlado at Chaosgroup, letting us in behind the scenes of the development of VRAY. Even if you use other renderers this gives an insight in what it takes to create and maintain one!
The job you have to do to incorporate new things, that did not exist when VRAY started, into the new versions to gain render speed. And the problems you have to solve when artists/users insist on doing not physically accurate things …?
I really loved this talk! I wish more developers would take after Vlado and share things this way!
