I made a texture for V4's iris using Photoshop, loaded it in the Material Room and rendered it.  Now take a look at the rendered image versus the unrendered image. 

(Click to enlarge)

See how in the rendered image, the texture looks blurred?  The dark little dark spots are gone.  Can anyone show me how I can stop this blurring?

To be totally honest, that blur is much more realistic unless you are doing a very extreme closeup of the iris.

preview mode and render view are totaly different, if you have a texture preview of 4096 and a poor render the preview will be better it's logic ... now try a high end render, it result the render look better than the preview ...

You have to take account that there is another layer on top of iris, the cornea.
preview mode does not display transparency in same way a render does.

It could be you want to turn off texture filtering, or render with a lower Min Shading Rate.

BB your eye is to real. it wont look good in poser hehe

Also the post-process filter in the Render Setting dialog lower right area... default is mushy "box" IRC. Try "sinc" which is more crisp.

The pupil looks pale on my LCD... do you need to fix the setting on the transparent eye material?

BTW Still do textures need to be 512x512, 1024x1024 etc. not to be re-sampled for the render?

Also... is their a way to force a Max Texture size in Poser 8 to get that setting like was possible in Poer 5? I loved being able to set Max Texture size in Poser 5.

BB, that is one of the best I've seen.... did you use image maps or is it all procedural?

That is Poser.

[Edit] Oh wait, I think I understand you. You mean it won't look good in Poser surrounded by typical Poser content? LOL

It uses the standard eye texture that SaintFox made for Antonia, and also procedural shaders for enhancing the depth of the iris details in the texture, doing realistic Fresnel refraction and reflection, and implementing the "limbus", which is the connective tissue between sclera and cornea, which happens to make the iris rim look dark (because it shadows it) and translucent (because the limbus transitions from sclera to cornea).

The geometry I made using my geomatic procedural mesh generating tool.

Whoa!  I would like to be able to do that.  But I'm still a noob.  :(

Actually, I AM trying to do an extreme closeup.

BB,

What the heck is being reflected (totally?) in the pupil?
It looks like the inside of Poser U. ??? :blink:  Has the eyeball been there?

Inquiring minds (like da NSG) want to know. :lol:

cheers,

;=]

P.S. Awsome looking eyeball BTW.

Oh ... cudda swore it looked like good ole Poser U., ha ha.

Thanks BB.

Thanks BB, that worked (texture filtering set to none).

Where do you set the texture filtering please?

In Poser 6, it's a render setting.

In Poser 7 and up, it's parameter on the ImageMap node holding the image in the material room. If you have the same image in many materials, you must adjust the texture filtering in every one.

There is a script floating around that will set all of the ImageMaps for you.  I'm not at my Poser system so I can't tell you who wrote it.  I'll try to remember to check when I get home.

It's SVDL's TextureFilter python script.  I don't remember if I found it here or over at RDNA.

img next to eye above (red tower and railing) also appears to be hdri-type img map.

Thanks BB I found it. Mine was set to the Quality setting and I changed it to None.

Thanks, I will follow that up.

Bagginsbill, you are too clever for me. Magic, just magic.
