Heya,

is there a way to use the realistic eye shader with raytraced translucency? Currently the occlusion shader makes the eye go completely black when switching from raster based translucency to raytraced.

This issue has been raised before here:

> If you need it to work, toss it into the forward shader so it doesn’t use ray tracing. if you are just bringing up the fact it doesn’t work correctly… yes. It’s been an issue reported numerous times on here. The last topic I remember on it had an issue tracker number - if you can spot it you should log in and vote on it. As far as end result, you would really have to look up close to notice the difference on this tiny detail between ray traced and not raytraced - were it not for the shadowin…

and there is a bug tracker for it that says it’s fixed but I have tested and it is still broken. UE-87521

Is anyone else having this issue?

Thanks
