Forward+ Rendering Path

The Forward+ Rendering Path lets you avoid the per object limit of the Forward Rendering Path.

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.
  The per-Camera limits for different platforms are:

  • Desktop and console platforms: 256 Lights
  • Mobile platforms: 32 Lights. OpenGL ES 3.0 and earlier: 16 Lights.
  This let's you avoid splitting big meshes when more than 8 lights affect them.

• Blending of more than 2 reflection probes.

• Support for multiple Lights when using Unity Entity Component System (ECS).

• More flexibility with procedural draws.

How to select the Forward+ Rendering Path

To select the Forward+ Rendering Path, use the property Rendering > Rendering Path in the URP Universal Renderer asset.

When you set the Rendering Path to Forward+, Unity ignores the values in the following properties in URP Asset, Lighting section:

• Main Light. With Forward+ the value of this property is Per Pixel regardless of the value you select.

• Additional Lights. With Forward+ the value of this property is Per Pixel regardless of the value you select.

• Additional Lights > Per Object Limit. Unity ignores this property.

• Reflection Probes > Probe Blending. Reflection probe blending is always on.

Limitations

The Forward+ Rendering Path has no limitations compared with the Forward Rendering Path.
