### Built-in Render Pipeline
To apply FSR2 to a camera, simply add the `Fsr2ImageEffect` script to your camera game object. It should be placed at the bottom of the components list, to ensure that it's the last image effect in the chain.

### Post-Processing Stack V2
FSR2 for Unity is also available as a full integration into the Post-Processing Stack V2 (PPV2) from Unity. This integration gets closer to the ideal placement in the render pipeline [as recommended by the FSR2 documentation](https://github.com/GPUOpen-Effects/FidelityFX-FSR2#placement-in-the-frame). The post-processing effects from PPV2 are split into groups before and after upscaling, meaning that effects that should be applied at full resolution (e.g. film grain, bloom, depth of field, motion blur) are indeed applied on the full resolution upscaled image.
Post-Processing Stack V2 with FSR2 is intended to be used as a drop-in replacement package for the official PPV2 package from Unity. It can be [downloaded from the Releases page](https://github.com/ndepoel/FSR2Unity/releases/latest) and should be extracted into the `Packages` directory of your project. From there it will automatically get picked up by Unity when you refresh your project.
When the package is installed correctly, FSR2 should appear as an Anti-aliasing Mode on the Post-process Layer component:
From here you can configure the usual FSR2 settings, including quality mode, sharpness, exposure and reactive mask.
### Callbacks
### Callbacks
FSR2 for Unity requires the application to provide a few services that it can't make any assumptions about itself. For this purpose, it exposes an `IFsr2Callbacks` interface with a default implementation `Fsr2CallbacksBase`. The application can provide these callbacks by either implementing the `IFsr2Callbacks` interface or inheriting the `Fsr2CallbacksBase` class and overriding one or more methods. Assign these callbacks to the `Callbacks` property on the `Fsr2ImageEffect` script component, before the script is enabled.
