Quote - Is it unusual for a 3D rendering engine not to have any kind of built-in option for handling something like the fresnel effect?
Yes it is. Poser has the Fresnel node, but that is only correct for clear materials that have 0 opacity or color. The Fresnel effect happen on everything that is even slightly shiny. For example, any sort of finished wood.
Quote - Just tinkering around, I notice that the source of the slowness of the shader is the raytrace node which is plugged into alt_diffuse. Is there any way to fake the desired effect for greater speed? Substituting a sphere map node with a reflection map doesn't seem to help.
Are you sure? Sphere map works very fast for me.
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)
