I have a little Problem,
I want make a Fish Tank who works like a single world and the Sun out of the FishTank don´t effects objects in the FishTank.
In the other way, the Sun should affect all objects but not the objects in the FishTank…
If I turn off the DirectionalLight to don´t affect the world, everything is dark and my spotlights work perfect, but all things out of the FishTank are dark too…
If the DirectionalLight is turned on to affect the world, I can see rising up the sun in the FishTank, it´s the same when I build a wall between the Sun and the FishTank…
How can I say the Lights, they should only affect specific objects?
