I'm fighting with my scene where I want to show some kind of portal. All scene has illuminated by hdri №1. The objects behind the 'glass' (object with 100% transparency) should be illuminated by hdri №2. I'm using light path node to separate two 'worlds'visually and it works (according the shadows), but object behind the glass (box) has very weak impact from his hdri. It looks like settings of transparent material somehow affected the image behind or maybe transparency of it is not 100% transparent.
I don't want use compositing for this effect because of realistic effect I'm trying to achieve, so it would be great if someone you guys could share some thoughts or links that might help
cegaton Thank you very much for your help, advice and links! Especially for pointing at sockets colors. Now I'm digging both articles.
I changed the node tree using color mix node and set the Light Path node to Transparent Depth (and glass material set to transparent BSDF), and, unfortunately nothing has changed. :,-( The objects behind the glass now still highlighted poorly in comparsion with hdri connected straight to the output node. It looks like hdri is loosing it's light intensity in this case
