Alpha 8 and high poly eye -- texturing

Postby SaltyCowdawg » Wed Sep 04, 2013 3:31 pm

So.. what's the trick? All I can get is black orbs inside the eye socket. Or worse all white "zombie eyes."

You should better describe what you are doing. What system are you using, and add a screenshot and the log.

OK.. when I get home later tonight I will post something more complete. Hoped it would be a quick answer.

Here's the highlights of what I'm doing:



Blender 2.6x using Cycles

Node setup where I'm using the eye color PNG file that gets exported for the eye as an image texture

Adding in glossy shader with image texture as input


Not getting anywhere near the results I'd have expected. I'm posting this from work and don't have access to my blend file at the moment.

So the problme is not in MH, but in Blender, after you export/import the model?

Sorry it took so long to get back to this... but here is what I was referring to:

I used the eye color image to texture the eye. Looked at the UV and it looked good but the eye does not render correctly in Cycles.

Maybe normals are inverted?

I've included the blend file. I'll take a look myself when I'm (finally) home tonight. Hope I remembered to pack the textures.. :-)

Looks like the cornea has lost its transparency.

I'm not sure why I didn't think of this earlier but I messed around with adding an alpha to the mix.

node setup in cycles for Lilibeth's green eyes


This produced much better results as here:

There are still strange artifacts that I have not been able to figure out how to get rid of, or where they are coming from.
