Hệ Thống (System)

The System section allows you to set graphics card options, memory limits & sound settings.

If your hardware does not support some of the options described on this page, then they will either not be displayed or be corrected on startup.

Thiết Bị Kết Xuất Cycles (Cycles Render Device)

Changes the computing device the Cycles render engine uses to render images. Cycles can use either the CPU or certain GPUs to render images, for more information see the GPU Rendering page.

Không (None): When set to None or when the only option is None: the CPU will be used as the computing device for Cycles.
CUDA: If the system has a compatible Nvidia CUDA device, it will be available as an option for rendering with Cycles.
OptiX: If the system has a compatible Nvidia OptiX device, it will be available as an option for rendering with Cycles.
HIP: If the system has a compatible AMD HIP device, it will be available as an option for rendering with Cycles.
Kim loại (Metal): If the system has a compatible Apple Metal device, it will be available as an option for rendering with Cycles.

Phân bổ bộ nhớ trên các thiết bị (Distribute Memory Across Devices): Allocates resources across multiple GPUs rather than duplicating data, effectively freeing up space for larger scenes. Note that in order for this option to be available, the GPUs must be connected together with a high bandwidth communication protocol. Currently only NVLink on Nvidia GPUs is supported.
MetalRT [Thử Nghiệm] (MetalRT [Experimental]): MetalRT for ray tracing uses less memory for scenes which use curves extensively, and can give better performance in specific cases. However this support is experimental and some scenes may render incorrectly.

Các Sắp Đặt của Hệ Điều Hành (Operating System Settings)

Biến thiết đặt này thành Blender mặc định của bạn.

Ghi chú

This panel of options is only available on Microsoft Windows.

Đặt Làm Mặc định (Make Default): Make the currently in use Blender installation the default for generating thumbnails and the default for opening blend-files.

Bộ Nhớ & các Giới Hạn (Memory & Limits)

Số Bước Hoàn Tác (Undo Steps): Number of Undo steps available.
Giới Hạn Bộ Nhớ Hoàn Tác (Undo Memory Limit): Maximum memory usage in Mb (0 is unlimited).
Hoàn Tác Toàn Cầu (Global Undo): This enables Blender to save actions done when you are not in Edit Mode. For example, duplicating objects, changing panel settings or switching between modes.

Cảnh báo

While disabling this option does save memory, it stops the Điều Chỉnh Thao Tác Trước Đây (Adjust Last Operation) panel from functioning, also preventing tool options from being changed in some cases. For typical usage, its best to keep this enabled.

Trình Phối Hình (Video Sequencer)

Giới Hạn Bộ Nhớ Đệm (Memory Cache Limit)

Upper limit of the Video Sequencer and Movie Clip Editor memory cache (in megabytes). For an optimal Clip editor and Sequencer performance, high values are recommended.

Sử Dụng Bộ Đệm Nhớ trên Đĩa (Use Disk Cache)

Writes cached strips to disk which can store a lot more than RAM. To use the Disk Cache, this option must be enabled, the Disk Cache Directory and Disk Cache Limit set, then save or reopen the existing blend-file.

Thư mục (Directory)

The location on disk to store the cache.

Giới Hạn của Bộ Nhớ Đệm (Cache Limit)

Upper limit of the Video Sequencer's disk cache (in gigabytes), setting to zero disables disk cache.

Nén (Compression)

The level of compression to compress image in the disk cache. This has a trade off between saving disk space and requiring more processing. The more compression used requires faster disk write/read speeds and more CPU usage.

Bố Trí Đại Diện (Proxy Setup)

When and how Proxies are created.

Tự Động (Automatic): Xây dựng bản đại diện cho các đoạn phim và hình ảnh được cộng thêm vào, trong mỗi kích thước duyệt thảo đã định.
Thủ Công (Manual): Thiết lập các bản đại diện một cách thủ công.

Âm Thanh (Sound)

This panel contains the sound settings for live playback within Blender and are only available with a device other than None. To control these settings for exporting sound see the Encoding Panel and Audio Panel.

Thiết bị Âm Thanh (Audio Device)

Sets the audio engine to use to process and output audio.

Không (None): No audio playback support (audio strips can still be loaded and rendered normally).
CoreAudio: On macOS, CoreAudio is the native audio API. This is the default setting for macOS users and should be preferred.
(PulseAudio): PulseAudio is the most commonly used sound server on modern Linux distributions. If PulseAudio is available, this should be the preferred setting on Linux.
(WASAPI): On Windows, WASAPI is the native audio API introduced with Windows Vista. This is the default setting for Windows users and should be preferred.
Jack: High quality professional audio engine that needs a properly configured server running on your system. Supports accurate synchronization with other professional audio applications using Jack.
Open Graphics Library, Thư Viện Đồ Họa Mở (OpenAL): Available on all platforms in case the native engines do not work. The played back 3D audio might sound different than when rendered.
SDL: Uses Simple Direct Media Layer API from libsdl.org which supports all platforms. Might be of lower quality and thus should only be used as backup.

Kênh (Channels)

Sets the audio channel count.

Bộ Đệm Pha Trộn (Mixing Buffer)

Sets the number of samples used by the audio mixing buffer. Higher buffer sizes can cause latency issues, but if you hear clicks or other problems, try to increase the size.

Tấn Số Mẫu (Sample Rate)

Đặt tần số lấy mẫu cho âm thanh.

Định dạng mẫu vật (Sample Format)

Sets the audio sample format.
