Render with transparent background

[niko_roncevic]

Hello.
I tried many times, but it seems I'm too mentally challenged to get it right, so I'm asking for help!
In the attached render, i used vray sun and sky. I would like to keep the light and get an invisible background, so that i can add it in photoshop later.
Please write me a walkthrough
Bonus question: is it possible to change the reflection on the display on the left also?

Thank you,

Niko

create a dome light, put your sky map in it, remove your sky map from environment, make a domelight invisible. Done.

Plus, make sure your glass shader has 'affect channel' set to +alpha also.
For the tv reflection, either stick an hdr in the environment (F10) reflection override slot or the tv material's environment slot.

Make sure your hdri is set to Spherical Environment. Slate Material Editor > HDRI bitmap > Coordinates > Environ > Spherical Environment.
