Bộ Nhớ Đệm (Cache)¶

Thể Loại (Type):: Phạm Vi (Domain)

The Cache panel is used to Bake the fluid simulation and stores the outcome of a simulation so it does not need to be recalculated.

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

If the mesh has modifiers, the rendering settings are used for exporting the mesh to the fluid solver. Depending on the setting, calculation times and memory use might exponentially increase. For example, when using a moving mesh with Subdivision Surface as an obstacle, it might help to decrease simulation time by switching it off, or to a low subdivision level. When the setup/rig is correct, you can always increase settings to yield a more realistic result.

Ghi chú

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

Thư Mục Bộ Nhớ Đệm (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.

Thể Loại (Type)

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

Chơi Lại (Replay): The cache will be baked as the simulation is being played in the viewport.
Mô-Đun-Hóa (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).
Toàn Bộ (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.

Quan trọng

"Chơi Lại" only works when the Chế độ Đồng Bộ Hóa Chơi Lại (Playback Sync mode) is set to "Chơi Mọi Khung Hình". If you need to use "Nhảy Cách Khung Hình" or "Đồng Bộ Hóa với Âm Thanh", consider using the "Mô-Đun-Hóa" or "Toàn Bộ" options below.

Khởi/Đầu (Start): Frame on which to start the simulation. This is the first frame that will be baked.

Cuối/Kết Thúc (End): Frame on which to stop the simulation. This is the last frame that will be baked.

Ghi chú

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.

Dịch Chuyển (Offset): Độ dịch chuyển khung hình được sử dụng khi nạp mô phỏng vào từ bộ đệm nhớ. Nó sẽ không được xem xét đến khi nướng mô phỏng, song chỉ khi nạp vào thôi.

Sử Dụng Bộ Nhớ Đệm Tái Phục Hồi và Tiếp Tục được (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.

Định Dạng Tập Tin Thể Tích (Volume File Format)

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

Bộ Nhớ Đệm Uni (Uni Cache): Blender's own caching format with some compression. Each simulation object is stored in its own .uni cache file.
Tập Tin OpenVDB (OpenVDB): Advanced and efficient storage format. All simulation objects (i.e. grids and particles) are stored in a single .vdb file per frame.

Định Dạng Tập Tin cho Khung Lưới (Mesh File Format) Duy Chất Lỏng (Liquids Only)

File format for the mesh cache files.

Đối Tượng Nhị Phân (Binary Object): Mesh data files with some compression.
Object (Đối Tượng): Simple, standard data format for mesh data.

Nướng Toàn Bộ, Phóng Thích Toàn Bộ (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.

Cao Cấp (Advanced)¶

Nén Thể Tích (Compression Volumes) Duy OpenVDB (OpenVDB Only)

Compression method that is used when writing OpenVDB cache files.

Không (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.

Độ Chính Xác của Thể Tích Duy OpenVDB (OpenVDB Only)

Precision level that is used when writing OpenVDB cache files.

Toàn Phần (Full): Volumetric data (e.g. grids, particles) will be written with full precision (32-bit).
Một Nửa (Half): Volumetric data (e.g. grids, particles) will be written with half precision (16-bit).
Nhỏ (Mini): Volumetric data (e.g. grids, particles) will be written with mini float precision (8-bit) where possible. For cache data where this is not possible, 16-bit floats will be used instead.

Xuất Khẩu Tập Lệnh 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.
