That was exactly it, thanks!

Hello,

I'm using Mantra for the first time and I'm having a bit of an issue getting my character's eyes to render correctly. My eyeballs are set up with the usual two pieces of geometry and the outer transparent surface turns the eyeball black. I'm using a principled shader core for the eye exterior with refractions and fake caustics turned on. I also tried using a classic shader core. The interior eye is using a principled shader with a metallic iris and subsurface turned on. I tried turning off the shadows using this tutorial: https://www.youtube.com/watch?v=xd7YMpTMZP8 [www.youtube.com]

Using the method in the video, I was able to get the iris to render correctly, but the eye whites are still black. I feel like there's a setting I'm missing like ray depth that's causing this. Any help would be appreciated, thanks!

Nice find Wojciech. I am unfortunately having the same problem. I can use the method described to apply displacement to, say, a sphere but it doesn't work with objects that I bring in. In fact, changing the radius on my object doesn't update the IPR like changing the radius on the sphere object does.
