Sistema

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 show up or be corrected on startup.

Preferences System section.

Cycles Render Device

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

Nenhum

When set to None or when the only option is None: the CPU will be used as the computing device for the Cycles Renderer.

CUDA

If the system has a compatible NVIDIA CUDA device, it will show up an option for rendering with Cycles.

OpenCL

Caso o sistema possua um dispositivo compatível com OpenCL do fabricante AMD, ele será mostrado como uma opção para utilização na renderização através do motor de renderização Cycles.

Memory & Limits

Undo Steps

Number of Undo steps available.

Undo Memory Limit

Maximum memory usage in Mb (0 is unlimited).

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.

Aviso

While disabling this option does save memory, it stops the Redo Panel from functioning, also preventing tool options from being changed in some cases.

For typical usage, its best to keep this enabled.

Sequencer Cache Limit

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

Console Scrollback Lines

The number of lines, buffered in memory of the console window. Useful for debugging purposes and command-line rendering.

Texture Time Out

Time since last access of a GL texture in seconds, after which it is freed. Set this to 0 to keep textures allocated.

Garbage Collection Rate

Number of seconds between each run of the GL texture garbage collector.

VBO Time Out

Time since last access of a GL Vertex buffer object in seconds after which it is freed (set to 0 to keep VBO allocated).

Garbage Collection Rate

Number of seconds between each run of the GL Vertex buffer object garbage collector.

Som

This panel contains the sound settings for live playback within Blender and are only available with SDL or OpenAL. To control these settings for exporting sound see the Encoding Panel and Audio Panel.

Dispositivo de áudio

Define o motor de áudio a ser usado para processar e gerar a saída de áudio.

Nenhum

Sem suporte a áudio (mesmo sem a saída de áudio, as faixas de áudio podem ser carregadas normalmente)

SDL

Usa a camada simples de mídia direta provida por libsdl.org para renderizar os sons diretamente para a saída do dispositivo de som. Muito útil para a edição de faixas no Editor de sequências de vídeo.

OpenAL

Provides buffered sound rendering with 3D/spatial support. Used for 3D source support by Speaker Objects.

Canais

Sets the audio channel count. Available options are: Mono, Stereo, 4 Channels, 5.1 Surround, 7.1 Surround.

Contingenciamento de mistura

Sets the number of samples used by the audio mixing buffer. Available options are: 512, 1024, 2048, 4096, 8192, 16384, and 32768. Higher buffer sizes can cause latency issues, but if you hear clicks or other problems, try to increase the size.

Taxa de amostragem

Sets the audio sampling rate. Available options are: 44.1 Khz, 48 Khz, 96 Khz and 192 Khz.

Formato de amostragem

Define o formato das amostragens de áudio. As opções disponíveis são: Ponto flutuante de 32 bits, Inteiros de 8 bits sem sinal, Inteiros de 16 Bits com sinal, Inteiros de 24 bits com sinal, Inteiros de 32 Bits com sinal e Ponto flutuante de 64 bits.
