Shadows Through glasses
I'm modeling a human character that is wearing some glasses. I created the glass with the Refraction Option enabled in the Rentrace Option for the shader. The Refraction Index for the glasses is at 1.33. The problem is that there is no shadows that goes through the glasses when Refractions is active. Please note that the both images are rendered with Raytracing enabled in the Globals Render Options.
On the image on the top, has no Refraction. The One at the bottom has Refraction enabled.
Is there a way to fix that? The shader I'm using is an phong.
