I have tried restarting roblox studio, tweak lightning properties, check studio graphics level even restarting my pc and nothing worked.
(this bug also apears ingame and in other games aswell…)
I am pretty sure I never used unified lighting so I guess its an engine error. I will figure out how to send a report sooner or later since I am quite new to the forums.
Hey, I am having the same issue here. After a bunch of tests and stuff, I was able to figure out that Roblox is, for some reason, turning the lighting technology to Voxel rather than ShadowMap or Future. I have no idea why this happens; the only solution I could find is playing on the Microsoft version, which fixes it.
Try pressing Shift + F2 in the game and tell me the technology. If it says Voxel, we 100% have the same issue.
