Toggling renderer.shadow after initialisation breaks the render, same happens when setting scene.environment to null after it's been set initially

[Samsy]

Description

Multiple cases breaks the render after it's been initially set :

Case 0 =>
renderer shadow was enabled, but then turned off later => blacks results

Case 1 =>
renderer shadow was off, but then turned on later => blacks results

Case 2 =>
environnement was enabled, then set to null later => black result

The live fiddle provide cases for each in the init function, to test =>

Change the CASE constant to either 0 / 1 / 2 and 3
