local lookVector = -camera.CFrame.LookVector
lookVector = Vector3.new(lookVector.X, 0, lookVector.Z)
lookVector = (CFrame.new(part.Position, part.Position + lookVector) * CFrame.Angles(math.sin(math.rad(math.round(handle.Position.X.Scale*100))), 0, 0)).LookVector

Thanks!

Can’t really simplify this without knowing what it’s supposed to do.

local lookVector = -camera.CFrame.LookVector
lookVector = Vector3.new(lookVector.X, 0, lookVector.Z)
lookVector = (
	CFrame.new(
		part.Position,
		part.Position + lookVector) * 
	CFrame.Angles(
		math.sin(
			math.rad(
				math.round(handle.Position.X.Scale * 100))), 
		0, 
		0)
	).LookVector

Here’s a start:

local lookVector = -camera.CFrame.LookVector
lookVector = (CFrame.new(Vector3.new(0,0,0), Vector3.new(lookVector.X, 0, lookVector.Z)) * CFrame.Angles(math.sin(math.rad(math.round(handle.Position.X.Scale*100))), 0, 0)).LookVector

What it’s supposed to do:
The sun is supposed to always follow the player’s camera, but behind. So in theory the player can never see shadows. But if the player looks up, it would be night time, so that’s why there’s a slider for the sun height :smiley:

#4 
local height = math.sin(math.rad(math.round((1-handle.Position.Y.Scale)*100)))
	
local lookVector = -camera.CFrame.LookVector
lookVector = (CFrame.new( Vector3.new(0,0,0), Vector3.new(lookVector.X, 0, lookVector.Z) ) * CFrame.Angles(height, 0, 0)).LookVector

Any good way to simplify the following?

CFrame.new(Vector3.new(0,0,0), Vector3.new(lookVector.X, 0, lookVector.Z))

Thanks!

Could you not just simply deactivate GlobalShadows property in lighting to achieve the same effect?
And if you also want to hide the sun you could also deactivate the CelestialBodiesShown property in the skybox. (found inside lighting)

Not quite, as one side of a part will be darker, regardless of shadows. The darkness makes it harder to see the texture and edges of a part.

Thank you for the “deactivate the CelestialBodiesShown property” tip though! :D
