How do you use 2D and 3D lights in Unity simultaneously?

@YOYBROYy You'll need 2 cameras for this and you'll need to get the Light Weight Render Pipeline. Once you've setup your Render pipeline, you can add both renders to the pipeline you've created. Next, you'll need two cameras. Camera "A" will render all of your sprites and Camera "B" will render your 3D assets. Camera "A" will need to be an overlay camera and Camera "B" will need to be your base camera. Once you've setup everything up, simply hit the plus button on the camera in the section for "Stack", then add your overlay camera to it. You should now have both 3D and 2D lights interacting with 3D objects and Sprites.
