Панель Cache використовується для запікання – Bake симуляції флюїду та зберігає результат симуляції так, що його не потрібно перераховувати.

Baking takes a lot of compute power (hence time). Depending on the scene, it is recommended to allocate enough time for the baking process.

Якщо сіть має модифікатори, то устави рендерингу будуть вживатися для експортування цієї сіті в рішальник флюїду. Залежно від устав цієї ситуації час обчислення та вживання пам’яті може експоненціально зрости. Наприклад, коли вживається рухома сіть з модифікатором Subdivision Surface як перешкода для зменшення часу симуляції може допомогти його вимикання або задання більш низького рівня підподілення. Коли такий уклад/оснастка коректний, то ви можете завжди збільшити цю уставу для отримання більш реалістичного результату.

Примітка

Fluid simulations use their own cache. All other physics simulations make use of the General Baking operators.

Каталог Кешу – Cache Directory

Directory to store baked simulation files in. Inside this directory each simulation type (i.e. mesh, particles, noise) will have its own directory containing the simulation data.

Тип – Type

The type of the cache determines how the cache can be baked.

Replay

The cache will be baked as the simulation is being played in the viewport.

Modular

The cache will be baked step by step: The bake operators for this type are spread across various panels within the domain settings (e.g. the bake tool for the mesh can be found in the Mesh panel).

All

The cache will be baked with a single tool. All selected settings will be considered during this bake. The bake tool for this type can be found in the Cache panel.

Старт – Start

Frame on which to start the simulation. This is the first frame that will be baked.

Кінець – End

Frame on which to stop the simulation. This is the last frame that will be baked.

Примітка

The simulation is only calculated for positive frames between the Start and End frames of the Cache panel. So if you want a simulation that is longer than the default frame range you have to change the End frame.

Offset

Frame offset that is used when loading the simulation from the cache. It is not considered when baking the simulation, only when loading it.

Use Resumable Cache

Extra data will be saved so that you can resumed baking after pausing. Since more data will be written to drive it is recommended to avoid enabling this option when baking at high resolutions.

Volume File Format

File format for volume based simulation data (i.e. grids and particles).

Uni Cache

Blender’s own caching format with some compression. Each simulation object is stored in its own .uni cache file.

OpenVDB

Advanced and efficient storage format. All simulation objects (i.e. grids and particles) are stored in a single .vdb file per frame.

Файл Формату Сіті (лише для рідин) – Mesh File Format Liquids Only

File format for the mesh cache files.

Binary Object

Mesh data files with some compression.

Object

Simple, standard data format for mesh data.

Запекти Усе, Вивільнити Усе – Bake All, Free All

This option is only available when using the Final cache type. Bake All will run the simulation considering all parameters from the settings (i.e. it will bake all steps that can be baked individually with the Modular cache type at once).

The progress will be displayed in the status bar. Pressing Esc will abort the simulation.

Once the simulation has been baked, the cache can be deleted by pressing Free All. It is not possible to pause or resume a Bake All process as only the most essential cache files are stored on drive.

Просунуто – Advanced

Compression Volumes OpenVDB Only

Compression method that is used when writing OpenVDB cache files.

None

Cache files will be written without any compression.

Zip

Cache files will be written with Zip compression. Effective but slower than Blosc.

Blosc

Cache files will be written with Blosc compression. Multithreaded compression, similar in size and quality to Zip compression.

Precision Volumes OpenVDB Only

Precision level that is used when writing OpenVDB cache files.

Float (Full)

Volumetric data (e.g. grid values, particle positions) will be written with full precision (32 bit).

Float (Half)

Volumetric data (e.g. grid values, particle positions) will be written with half precision (16 bit).

Експорт Скрипту Mantaflow – Export Mantaflow Script

Export the simulation as a standalone Mantaflow script when baking the scene (exported on «Bake Data»). Usually, only developers and advanced users who know how to use the Mantaflow GUI will make use of this functionality. Use a Debug Value of 3001 to enable.
