What are you attempting to achieve? (Keep it simple and clear)
A window that changes transparency and colour depending on which side you look at it from (I don’t mean iridescence though.}
What is the issue? (Keep it simple and clear - Include screenshots/videos/GIFs if possible)
A window can’t be both colours.
What solutions have you tried so far? (Have you searched for solutions through the Roblox Wiki yet?)
I think this would involve scripting but still, how would you change the colour without other players seeing it? I’m assuming local scripting?
Examples of the window. Ignore the text because it was hard to capture them without being arrested.
From the outside:
I assume it would be a local script for the clients that would update the window transparency/colour dependent on the magnitude, e.g. if the magnitude from the window to the player is >/< then make it more transparent/more opaque for the client.
You can place a decal OR… in a more derp way because it’s derp you can use
CFrame:PointToObjectSpace
Example
local CFramee = workspace.Door.CFrame:PointToObjectSpace(HumanoidRootPart.Position)
if CFramee.Z > 0 then
print('Front!')
elseif CFramee.Z < 0 then
print('Back!')
end
