Sudden light shift when camera is moved

So I just ran into this issue, here is a video showing exactly what happens:

I have a camera looking into a hole for a cut-scene and every time the camera snap to the cut scene position there is this shift in light. In the example it happened when I exited play test (I start play test from the exact point of view so when I quit it I go back to it and the issue occurs) but the same effect occurs during the cut scene in game.

So far I have tried to remove the instances inside Lighting and it didn’t change anything. I’m almost positive it’s not script related, I tried to put the pieces of code which move the camera apart and the same issue occurs.
One thing that I have noticed is if the hole is located closer to the original camera position it no longer occurs.

The issue is that the cut-scene will supposedly trigger from all around the map so the cut scene hole won’t always be close by and this light change really kills the mood.

Is this a feature that i can disable, or a known occurrence, and is there a workaround ? Or is it just like that ?

it’s likely due to how Roblox handles lighting and environment changes when the camera moves far distances suddenly. One workaround I found is to preload the area or move the camera gradually instead of snapping it instantly. Also, try setting the Lighting’s Technology to Compatibility or ShadowMap and see if it reduces the light shift.

Maybe even file an issue in the engine topic, might be helpful if the issue keeps occurring

Thanks for the quick response ^^.

I tried different Technology, Voxel and Future did worse, instead of a light shift I got a sudden change of light, for Compatibility I just checked and it’s Deprecated.

But I found a way around, I had a Black screen fade in and out playing during which the camera get teleported, I tweaked some task.wait in order to have the color shift happen when the screen is still black. Still thank for the proposition.

I’ll probably open an issue but maybe it is already a known/Intended one so I’ll need to search before and I am a bit lazy right now.
