Should I post it as is? I'm still not certain I have position and rotation correct.
Also, I did some very exacting measuring today.
If we assume the Poser scale of 1 PNU = 8 feet or 96 inches (not the current 103.2 inches which I now reject even though that is the conversion in Poser Inches), then according to my measure, the existing Antonia eye is much too big, which is why I had to decrease the size of the iris and cornea to the point where they are not anatomically correct with the eye, but are almost correct with the face.
Antonia's eye diameters are
Height or Width: 1.284 inch = 32.62 mm
Depth: 1.356 inch = 34.45 mm
I found many sources of eye dimensions and they disagree somewhat, but all agree that the eye diameter is in the range 23.5 mm to 25 mm. And they all agree that the cornea diameter is about half the eye, or around 12 mm.
My cover object, which is more than the cornea (includes the "limbus" - the connective tissue between sclera and cornea) is 15.24 mm, making my cornea about 13 mm, slightly too large. But it's about the same as the old Antonia eye. (I didn't measure the old cornea exactly.)
I'm troubled by this. The eye should not be this big. I believe it is the reason why I do not see what I expect to see with regard to falloff of lighting on the sclera. It seems like it's too flat, because the sphere is too large. Thoughts? Is it possible to change the eye size to a proper 25mm, and adjust the eyelids to match? (You'd have to bring the outside corners in a bit.)
Also, I have questions about the proper implementation of the pupil dilation morph. I read you guys a while back saying morphs should not come in at non-zero values. But the pupil dilation morph works best if you start with contracted pupils (at 0) and then dilate the pupil from there, with .5 being the "normal" or typical state. Here they are at .5. Thoughts?
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)
