How to Control shaders?

Hi, I have an issue and a question at one time.

I spotted , that when scene reloading in unity editor due debugging, shaders goes crazy.

So, why it’s happening ( in builded game it’s not happening), and how to switch this contrast manualy? coz I like it!

This is the difference ambient lighting makes. When the scene loads, by default it scraps any ambient/GI calculations in the Editor and regenerates them. To achieve the effect of the bottom screen, simply go to the Lighting window and set your ambient intensity to 0.
