Alright, so i’m making an update to my homestore and i decided to use the future lighting to make it look nicer. Everything was going well until i added my spawn points. When i went into testing the lighting seems to disspear or flicker, the avatar’s shadow also lags behind, these things dont happen when in building/studio mode. Only in test mode.

Can someone explain whats happening?

Heres another example

Edit:
3rd example (flash warning)

This seems more like a Roblox lighting, I don’t think you can fix it, at least
not until Roblox does. Maybe I’m wrong, I don’t do a ton of work with lights.

Are you many point lights? This is the main cause of these bugs.

Substitution of point lights with surface lights and lighting optimizations may fix this bug. I have had this bug too before. One way to optimize is by reducing the number of shadows present.
Here is some helpful code to optimize your shadows:

for i,v in pairs (workspace:GetDescendants())do
if v:IsA("BasePart") then
if v.Size.Magnitude <= 5 then
		v.CastShadow = false
		
	end
	end

end

what this does is removes the shadows of small objects in the map automatically.

Shadows acting weird

I mainly use surface lights so i guess it would be the same as using tons of point lights.

I’ll try your code, thank you!!
