Is it possible to implement 2D light on the interface without unnecessary hassle?
I tried to combine two cameras, one of which is the main one and renders 3D, and the second one only UI, but Unity prohibits superimposing cameras with different pipelines. As I understood after listing other similar questions, there was such a possibility in the Unity version before 2021.
I also found a way by changing the shader of UI objects to Lit, but firstly: for this you need to create a separate material that will be white, it would seem that the matter is - superimpose a sprite and the problem is solved, but you cannot superimpose a sprite on the base map parameter of the material (with the Multiply sprite mod); Secondly: This solution uses 3D light.
