Same as this issue, which was closed despite not being fixed. MCPE-144060
Any model that is placed on the odd 16th block on the Y coordinate (15, 31, 63, 79, etc.) has broken shading.
Seems to be most prevalent with models that are larger than one block.
Turning Smooth Lighting off mostly fixes it, though you might get one black piece of geo here and there.
If this has something to do with it not getting light because it crosses the chunk boundary, perhaps it should try to get the light from the adjacent chunk once it's loaded in? (Just a suggestion for a possible fix.)
Attached is an .mcworld file with a test resource pack inside, and a map with a few placements of the block in question demonstrating the bug. Just load it up to reproduce the issue.
Expected result is for all of the custom paintings in the test world to be properly shaded, not having some be darkened for no reason.

But we did explain the issue and how to reproduce it? Did you even read any of this? Just place any block with > 3 block tall geo on any multiple of 16 y coord minus one. So, 15, 31, 47, etc.
And no, this isn't specific marketplace item. If it did, I would have said so. Anyway, I attached an .mcworld file, it'll have a world with a test scenario and the resource packs in question bundled inside.
Upon further inspection, this happens on X/Z coords too, if geo > 3 blocks in that direction. So it is indeed due to chunk boundaries. Hopefully the suggestion for a fix can actually be implemented.
Thank you for your report!

This issue does not seem to reproduce in the latest versions. Are you still experiencing it on your end? If yes, which platform are you playing on? Does changing Video settings have any effect?

Yes it still happens, and the video settings don't do much, disabling smooth shading sort of helps, but not completely. And the platforms I'm playing on are PC, Xbox, and Nintendo Switch, happens on all platforms.
Is this still an issue in the latest version? If yes, could you please add it to the affected versions (or mention it if you are not the reporter)?

I can't test it anymore because you guys killed > 3x3x3 blocks. The block geos in the screenshots get rejected by the game despite once being able to use them.
