I have Poser 6 and 8, i still use my P6 though. i have also come across this issue as well. with a texture not wanting to work, and  i usually go through that paces of the whole eye/body thing. i always double check, make sure it(the texture) holds. i'd go back to the main window and spot render it(area render).  I try this tactic  a few times, then if all fails i look for that next best color to bring out my chars, charactristics. most  of the time its usually comes out better then expected..

Now is your V3/V2 texture, compatible? is it for Poser 4 or Higher? I noticed some of those don't work well in Poser 6. My issue on this, was usually when i use a V3 texture on a A3 char. The texture worked ok, but the eyes were the problem spot with some textures not all. Of course i've been wingin' it with poser, since Poser 3. 

I currently use the V4/A4 char, but i still use the A3 aswell.  i can't leave my one of favorite chars, in the dust. well this is my ramble on the subject..

One more thing, remember most venders have almost the same eye color, yet their presentation of the eyes are different. So if one doesn't work try another.

Welcome back Dodger. I think, we use to type at each other in the chatroom  a few years ago.
