Light shines through walls when technology is set to Future

PROBLEM

When the lighting technology is set to Future, when a certain distance away, light from behind the walls will show through. What I expect to happen is for the light to not shine though the wall.

WHEN/WHERE

This happens all the time in Studio. It does not seem to happen in a live server.

REPRODUCTION

  1. Open the attach file in Roblox Studio.
  2. Run the file
  3. Move towards and away from the walls to see the bug.

We’ve filed a ticket to our internal database, and will follow up when we have updates!

Thanks for flagging!

That’s just the cut-off point for the high-quality shadows, where it turns back into regular old Voxel. It should leak through the walls the same way on the lowest graphics quality, since Future shadows are only enabled on graphics levels 4 and up.

If that’s the case, then is there a way to adjust that?

No, it’s there so that low-end machines don’t melt trying to render high-quality shadows. You could always increase your own graphics quality setting though.

The thing is though (and this was mentioned in the original post) is that this issue only occurs in studio, not in the live game. You would think that it would be the same.

It should be exactly the same as long as the graphics quality is exactly the same. Make sure it is, because I checked myself and the high-quality shadows still fade out at a short distance on graphics level 4 about half an hour ago (on Doors by the way).

This is also occuring for me.

That’s an actual bug, but it’s different to this thing. You can submit a bug report through Bug Support if you can’t post directly to #bug-reports.

Hi! This is indeed an inherent limitation of the Voxel lighting technology paired with our scaling system. We will close this ticket since we are not treating it as a bug, but we are tracking light leaks as a common pain points for developers in our feature requests list.
