I am trying to do a simple product shot of a glass. I want the background to be pure white. I have tried both setting the world to white and increasing the strength and setting the world to transparent. I really am not able to get a white background, and I have some weird problems when using transparency. Half the render turns out white, the shadow catcher is transparent, the glass is white. I would really like the glass to look like glass with the non-reflective parts transparent, and I would like the whole background to be transparent as well. This way I can add the white background in the compositor and have more freedom.
Can someone help? Blender-file attached.
