    We have holes in our terrain and use lightmapping, however the rays don't seem to enter beyond the terrain hole. If I remove the terrain it behaves correctly. Is this fixable in any way?

    We use 2020.2.5f1 with Built-in pipeline

    Thanks for the reply! Is this then also fixed for GPU baking? Also is there a chance it will be backported to the 2020.3 LTS version?

    The issue is fixed for both the CPU and GPU PLM. Backports have been initiated for version 2018.4, 2019.4, 2020.3 and 2021.1.

    Apologies, I mistook this bug case for another one. Backports hadn't been requested yet for the version you mention, so I have just opened requests. Cheers.

    Hey there. Unfortunately the backports of the fix in question got delayed, since said fix introduced a regression which must also be backported. This work should be unblocked now, but I can't exactly give an ETA. I've inquired about the status of the backports - I'll let you know if there are any news.

    Hi, sorry to bother but I was wondering if it is known if/when this will be backported at this time (in my case the interest is to 2019.4). I used some terrain holes in my level design and have big concrete tunnel coming out that is getting lightmap artifacts. I tried adding a plane in between the directional light source and the tunnel model in case that would help, but it did not and then I found this thread. Thanks for any new info you have.
