    Hi all! Im use last beta of 2019.3b6

    Every time when im try bake the light on my scene - its bake good everywhere ,but not on models under ground =(

    My light bake settings (No real-time GI) upload_2019-10-10_12-23-48.png
    The terrain has hole under building, but seems like baked light on terrain is good too upload_2019-10-10_12-25-53.png

    Hi

    Not really sure what the problem is here. Is the light meant to come in through the hole and lit up the downstairs area and not cause artefacts? If so, you really need to crank up your bounce and sample count :) Especially the indirect one. Hope that helps!

    Could be something as stupid as needing to use special lightmap settings on the terrain such as "Is Transparent".
