Paragon Phase: Eye Material Problem with Ray Tracing

[BernhardRieder]

I am using the Epic Character Paragon Phase.
When adding the character to my project, the Eye Material is black and odd when using Ray Tracing for Translucency / Refraction.

Here is a snapshot, how the eye should look like. Bright, and the color of the iris can be seen.




When I use Ray Tracing, my result looks like someone was beating her up very badly.... uuuahhhhh...


I was wondering what I need to change? I tried a few things, as such switching Translucency to Opaque. But nothing I tried worked.



Does anybody know how I can fix that problem?

Thank you so much for any little help,
appreciate it!

Have you tried to check off the box "Cast raytraced shadows"?

Well the problem is, I think, is the way the eye is modelled includes an outer cornea layer that requires a transparent layer. Raytrace shadows works better with transparent materials but in this the cornea is casting a shadow onto the inner eye layer making it look like the player has a black eye.Turning off cast shadow should fix the problem

Turning off shadows unfortunately doesn't solve the issue. I already posted a thread about it here:

What happens if you change the transparency to forward shading?
wondering if having it precompute at a different step would take it out of the ray trace shadow casting...
or at least change the magnitude of the effect... the eyelashes and the cornea could probably both use that.

Already tried, to no avail.

a little progress on that.. I was finally able to fix the Eyeball... see screenshot below...
but heck, now I am stuck with the Eyelashes.. I can't fix them using the same method....

any other ideas?

It's not the same thing at all (as the original transaprency), but you can do Opaque Maked if it corrects the shadow casting. You just have to deal with the fact the eyelashes won't ever be seethrough.

it's kinda hard to say though, I dont think disabling shadows is a good idea on lashes, and I think they need to have a way softer shadow decal to look natural.

try to see if any of the info in here helps for softening the shadow before just axing it. (Or possibly making it worse with opaque masked)

hmmm.. well, I tried to find a solution but not luck. I wonder how the eyelashes have been render and used for the Videos from Epic itself. They didn't seem to have a problem...
