Hi, I've started learning redshift, since my main area of activity is architectural visualisation and I found Mantra to be quite slow for interior rendering.
What I currently can't seem to get working, is Indirect environment lighting and portal lights.
I started off with a Houdini Environment Light (probably not the best choice, to use a dome light for interior lighting), placed Portals in my windows and everything worked relatively nicely, but when I tried to substitute the likely inefficient Dome light with an environment material, I'm getting no light in my scene whatsoever.
Could someone post a working scene with indirect lighting and portals in Redshift for me to dissect? Or explain to me in laymans term, step by step, how to get a working Indirect lighting setup with portal lights?
Also, I seem to be unable to change the sizes of the portal lights, unless I unlock the RS portal light asset and change the sizes of the grid geometry inside the asset, which seems weird to me. Also, why are there 2 grid meshes inside the portal light asset?
Thanks in advance.
