It's been a while since I did any lighting and rendering in Arnold and I wanted to brush up on it a little bit. One thing that's driving me crazy is getting glass to actually render transparent. I've been digging through quite a few posts, but haven't been able to solve it yet.
I have a really simple scene with a teapot sitting on a window sill. The lighting is a three-point light setup with Arnold area lights. The glass was created with an ai standard surface and a glass preset applied to it. The shape node on the glass has "opaque" unchecked and the normals are correct. Also, there's no skydome, stage, or anything else in the scene. Currently, my lights are unlinked from the glass, but I was having the same issue before even when they were linked (just wanted to mention in case it's relevant).
I want to render this out so that I can comp in a video of a backyard in post (but still get the reflection of the teapot on the glass). When I save my rendered image however, the glass is black (I've tried tiff, exr, and png file types).
Any thoughts on what I'm missing?
