  • Light select pass with Dome light doesn't show reflection or spec

    I have a scene with a few area lights and a dome light. If I disable the area lights, the light contribution is only from the dome light, which has an hdr mapped in. Now with this, should a light select element for this dome light look exactly the same as the beauty pass? My result is inconsistent. The light select element seems to only display diffuse lighting, with no reflection or specular components at all. Is this intentional? Is it not possible to get the entire light contribution in all channels, not just diffuse?

    if I recall correctly, a light select has - Raw, Normal and Specular. Normal being the diffuse component * lighting. Raw being just the raw and specular is just specular. In any case where you need to use light selects you need to always generate two light selects per light, one for diffuse one for specular.

    Reflection can't be separated per light since its considered indirect like gi.
