No, I'm not trying to get rid of it in a photograph, I'm trying to create it in Poser 7. Any suggestions on how to create this effect in the Materials room?

Thanks,

Guy

have you tried editing your texture map (copy) , so that you have a red colourized pupil area?

you could just add a circular red spot to your copy of the tex map and adjust the opacity slightly so that it is not a solid red, before merging layers.

if it is just a still image, then why not just add it in postwork?

Do you mean a red pupil?

If you're going to do it in post, get a real photo (or take one) with bad red-eye and use that.
Can't get any more real than that.
Hope that helps-

In the Material Room select the pupil then disconnect the Image Map node from the diffuse colour box and change the diffuse colour to red.

Thanks for the suggestions. I'm trying to do it all within Poser, not postwork, but I'm still playing around with the effect.

in humans, the pupil is the opening in the iris, hence it's just an empty space surrounded
by a circular muscle.  the red-eye fx is the flash illuminating the human retina.  but then,
I reckon poser figures must have a black pupil that's opaque, otherwise we'd see default
renders with both nostril glow and "retina glow" 🤣

Miss Nancy - your avatar has grown!
Exactly - it also has different hues - not just a blank red dot which will look cartoonish. I'm afraid that if it is made a "material" how much gets lighted/you will see will depend entirely on the lighting (unless the Materials Lab has a Luminance Channel - I'm blanking).

The closer a flash is to the lens, the more reflection you will get from the retina - which is why we only see it through the pupil.

I'm still thinking your best bet is postwork if you want it to look real - and years of family and friends' photos would be an almost endless supply.

Try this thread:

Cat's Eye Glow in Animation

The issue there was a cat's eye (green) not human, but the principle is the same.

I then tried it in an animation - the Poser cat's eye is not shaped great for this, but you get the point. It might work on your figure. Be aware that many figures have a cornea bulge morph. You may need to use that to improve the results.

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)

That's funky!

This is pretty close to what I'm looking for. Thanks for the heads-up, Bagginsbill!
