Question Desactivate super intense light

I installed Polybrush, and when I use the tools Sculpt on meshes and Smoth mess geometry a super intense light appears over the geometry off an object. I desactivated the Scene lighting button and the light doesn´t appear, but I saw videos where the button Scene lightning button is on and that light doesn´t appear.
How can I desactive the light when the Scene Lightning is on?
This one is the light I´m talking about:
And I want that light to don´t appear when the Scene Lightning is on (The light bulb activated):

 

What are you using for a terrain material/texture?. Even though it goes away when you cut scene lighting, doesnt mean its lighting involved. It looks like smoothness/metallic is turned up, or, theres alpha on in the import setting of the textures.

Dont know any further info about your project, so im just going by whats presented...
