Interior Render

[buildinthevoid]

So I have a pitched ceiling and not sure why but when I render/raytrace it, the soffits holding it up are lit up by the sunlight outside. How could I fix this issue?

You need to make certain that none of the beams penetrate beyond the interior drywall surface. It's a PBR problem if a material/object is both inside and outside, it will be lit according to the exterior light not the interior. A quick option is to turn off the sun.

And sometimes there is no control, like with this wall cap. The sunlight is way down and its still lighting the wall cap incorrectly. It's the same material as the c-top and the backsplash.

WRONG:

Here I replaced the wall cap with a manual molding, the same molding that was used for the wall cap, and the same material.
