This rollout is only available when the UHD Cache is set as the Secondary GI solver.
Preset
Still frame (fast precomputation) – Configuration with short precomputation that works great in still frames, but might flicker in animations.
Animation (flicker-free) – Configuration with longer precomputation that aims at eliminating flickering in animations.
Precision – Quality-time tradeoff for the UHD Cache. Lower values result in fast precomputation but can increase bias and flickering. Higher values give more precise, flicker-free results with longer precomputation. High values should be avoided, as they will also lower the success rate of the cache and make it less efficient during rendering phase.
Save/Load
Precomputation – Determines how the UHD cache for rendering is obtained:
Calculate from scratch – The cache will be calculated independently for each frame in a precomputation pass. Load from file – The cache will be loaded from the specified file instead of computing it. Good for animations as it prevents flickering. Load from file + append – The cache will be first loaded from the specified file, and then the precomputation pass will run on top of it. The loaded and computed caches will be merged. Good for animation precomputation (when ran e.g. every 30 frames).
After render – When set to "Save to file", the UHD cache will be saved to the specified file after rendering, possibly overwriting it.
Filename – Specifies the path where the cache file is saved to or loaded from.

This rollout is only available when the 4K Cache is set as the Secondary GI solver.
Preset
Still frame (fast precomputation) – Configuration with short precomputation that works great in still frames, but might flicker in animations.
Animation (flicker-free) – Configuration with longer precomputation that aims at eliminating flickering in animations.
Granularity – Increasing this value will lower memory usage, but it will result in more splotchy render.
Quality – Increasing this parameter will increase the precomputed GI quality, while increasing the precomputation time at the same rate.
Save/Load
Precomputation – Determines how the 4K cache for rendering is obtained:
Calculate from scratch – The cache will be calculated independently for each frame in a precomputation pass. Load from file – The cache will be loaded from the specified file instead of computing it. Good for animations as it prevents flickering. Load from file + append – The cache will be first loaded from the specified file, and then the precomputation pass will run on top of it. The loaded and computed caches will be merged. Good for animation precomputation (when ran e.g. every 30 frames).
After render – When set to "Save to file", the UHD/ 4K cache will be saved to the specified file after rendering, possibly overwriting it.
Filename – Specifies the path where the cache file is saved to or loaded from.
