    Hello everyone,

    i'm trying to use the 2D Light from URP for my projet, and I encountered a problem with the Custom Lit Shader I implemented : whenever there is no light in the camera (in fact, no light printed in the light texture), then the texture take a wrong default value or take it from the unity Scene. like the example below :

    as you can see, the light on the game (bottom screen), is the same than the one in the upper screen, instead of being just dark.
    And if no light from any camera, the scene is just not using any light, and rendering everything bright like below

    the shader light sampling look like that, the output being just multiplied by the sprite RGB

    Do you have already encounter this problem and know how to solve it? (I think I may do the sampling wrong)
    Or is it a bug in URP 2D Light?
