Hi, I’m trying to make a clear retina, but it seems it distorts a little too much.
In the first picture there is a ztransp retina and in the second there isn’t a retina piece at all.
Notice the high level of refraction, from a pretty straight on camera view (in the first picture):D.
This is blender internal renderer also, so I’m surprised there’s refraction at all LOL!
I would have been happy with pure transparency and a little reflection.
I like a little bit of refraction though, but is there a way to reign in the refraction,
to cut back on the droopy ‘fish eyed’ look?
Thanks for any advise!
Hey I’m not a doctor
Yeah it’s set to ztransp.
Here’s the ‘no shadow buffer’ retinal clear skin flap version;),
which I like better, but it’s completely transparent, except for the light reflection…
You’re right cire, it’s just a single sided retinal flap that I modeled, like a contact lens…
Is there a way to mess with the refraction in Blender Internal render?
I should have said “is it possible without raytracing”
That first one is Blender Internal without raytracing enabled, and it seems to refract.
It’s just an illusion though, I just rendered out from different angles, and definitely no refraction.
I see now its just the shadow buffer casting a weird shadow.
I’m making a lot of ‘no raytracing’ experiments, like environmental mapping for reflections,
as I have three very elderly computers…my good one has a fried motherboard,
and raytracing slows things down a lot.
The quality really suffers though, and I can’t wait to fix my good computer.
I thought I found a secret no raytracing refractions thing in BI here.
