FSR2TextureTable

Description

The set of texture slots available for the FSR2Context. SA GraphicsDevice.ExecuteFSR2.

Use this struct to specify input and output textures for the FSR2 implementation.

Note: You must create output color texture colorOutput with enableRandomWrite parameter set to true when initializing the T:UnityEngine.Rendering.RTHandle of the texture. This is due to FSR2 passes requiring access to the resources in a compute shader

Refer to the Input resources section in FSR2 Documentation for more details.
