      Hello everyone.

      I've been reading this forum for a while now. Great source of information.

      I am working on a rendering and I am having real issues with the glass material. As you see in the image on the right side the chair looks completely black through the glass as well as a black box next to it. I am not sure what is causing this. Never had this issue before. I have tried with different glass materials and all give me the same result. I know the glass as thick and not single face. However the angle of the rendering I'm afraid would look weird if the glass had no thickness.

      I am not sure what am I doing wrong. Any help would be highly appreciated.

        Make sure you don't have duplicate faces. It could be you have two glass objects for that panel.

          Thank you for your reply.
          Are you referring to having assigned the glass to both front and back face or 2 separate materials. I have checked and there are no duplicate faces. I have even deleted the panel and recreated it with no success.
          If I rotate the perspective, the shadows appear on the left panel instead of the right so the angle of the perspective affects it. I thought initially it might be the glass material I'm using but I have tried with several ones and they all seem to produce that shadow.

            If the glass has a refraction layer, check that the front/back faces are facing correctly. You may have a back face facing out. I tend not to use refraction for glass like this. I just use a simple plane with 95% transparent material with reflection layer.

              Well, it would probably be pretty quick to sort out if you posted just that piece of your model. Like valerostudio, I first thought backfaces, but you sounded pretty sure of your modeling, plus the view through the glass doesn't look badly distorted. I'm guessing it could be some issue with the refraction depth being too low value, but it's hard to know without the model to look at.
