 The Forward+ Rendering Path has the following advantages compared with the Forward Rendering Path:
 
-* There is no per-object limit for the number of Lights that affect GameObjects, the [per-Camera limit still applies](../urp-universal-renderer.md#real-time-lights-limitations).<br/>This implementation lets you avoid splitting big meshes when more than 8 lights affect them.

-There is a per-Camera limit which applies to the number of real-time lights in all rendering paths.
+There are per-camera limits on the number of visible lights in all rendering paths.
 
-As for the Additional Lights, the limit applies only to the Lights visible to the Camera.
+The Main Light always counts as visible.

+The per-camera limits for different Rendering Paths and platforms are:

+**Forward and Deferred Rendering Paths**:
 
 * Desktop and console platforms: 1 Main Light, and 256 Additional Lights.
 
 * Mobile platforms: 1 Main Light, and 32 Additional Lights.<br/>OpenGL ES 3.0 and earlier: 1 Main Light, and 16 Additional Lights.
 
+**Forward+ Rendering Path**:
+
+The Forward+ Rendering Path treats all lights (the Main Light and Additional Lights) the same way, which is why the per-camera limits are one light less than in the Forward and Deferred Rendering Paths.
