All subsurface passes within the screen-space subsurface effect can operate at half or full resolution, depending on the subsurface mode. The values are precomputed and shared among all Subsurface textures.

When in bypass mode, the setup and convolution passes are skipped, but lighting reconstruction is still performed in the recombine pass.

See the related comment above in the prepare pass. The scene viewport is used as both the target and texture viewport in order to ensure that the correct pixel is sampled for checkerboard rendering.
