Discussion

Use this RGBA texture to provide to the denoiser an overlay with your transparent pixels, such as the output of your particle systems. MetalFX interprets this to be a texture in linear color space, with the RGB channels ranging between 0 and infinity, and the alpha channel in the range [0,1], representing the opacity of the pixel.

You are responsible for ensuring the usage and pixel format of the texture you assign to this property matches the texture usage transparencyOverlayTextureUsage requests and the pixel format that transparencyOverlayTextureFormat requests.
