Quote - bagginsbill how could we make gamma corrected white plastic? plastic is a little reflecting right?
Shiny plastic is easy - but you must respect the simple facts of the Fresnel effect. If you set up uniform reflection intensity across the entire surface, you will fail at realism. Plastic reflects less when facing the viewer, and more when facing away from the viewer, sideways.
There are plastics that are so shiny they are effectively glass. Others are microscopically rough, but still smooth enough to reflect a little bit at the edges, not at all towards the camera. You must tune the Fresnel effect to compensate.
Just like the soft metal reflections we did in the past, ice-boy, we may have to use blurred reflection to get perfect realism.
Also, even white plastic does not perform 100% diffuse reflection, so don't put Diffuse_Value = 1. It should be about .8. I will build you a couple examples and you can work from there.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
