My blinn node is plugged into the alternative_specular node, and haseccentricity at 1.00 and sec roll off at 0.0006 and the reflectivity at 0.0007. I have no Gc at all and the lighting rig is simple-1 ibl light at 100% intensity, 1 grey main light at 50% intensity and one spot light at 57% intensity.

Don't use gray lights. Use white and adjust the intensity with the intensity dial.

The effective luminance of lighting is the product (multiplication) of the color and the intensity. Gray is a number less than 1. Talking about lights with an unspecified gray is pretty much the same as telling me nothing about your light. Plus, if you ever start using render GC, such light sets will be completely different, because the gray will be anti-gamma corrected, resulting in a different luminance. Get used to white lights, unless you're trying to make a colored light, like blue or red.

Your Blinn parameters are out of whack. But you wouldn't know it, because you have so little specular light and so much diffuse light. (Note: This is a Poser concept and has nothing to do with physics. There is only one kind of light in real life. The material decides to treat it as specular or diffuse.)

As a starting point, your Blinn values should be .4, .4, .4.  It's easy to remember that way. It's not perfect, but way better to start with than what you have.

Once you get things balanced, then we tweak.


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)
