Render ‣ Performance

Properties that affect render speeds or memory consumption. There are several presets available to help choose between different trade offs:

Default (по умолчанию)

Balances memory saving and faster rendering settings.

Faster Render

Uses settings to render faster at the cost of higher memory consumption.

Lower Memory

Uses settings to decrease memory considered at the cost of slower renders.

Потоки

Threads Mode

Method to determine the maximum number of CPU cores to use while rendering.

Auto-Detect

Automatically chooses the amount of threads to match the number of logical processors on your computer.

Fixed (фиксировано)

Manually choose the maximum number threads to use for rendering. This can be useful for example, if you want to use your computer while rendering, you can set the property to a thread count lower the amount of logical processors on your computer.

Потоки

The maximum number of CPU cores to use simultaneously while rendering.

Use Tiling

Render high resolution images in tiles to reduce memory usage. Tiles are cached to disk while rendering to save memory.

Tile Size

This value is used to control the size of the tile used for rendering; decreasing the size reduces memory usage.

Примечание

In some cases changing the Tile Size can result in increased performance. For example when a small object renders slowly compared to other objects, using a small Tiles Size can lead to an increase in performance.

Структура ускорения

Простр. разбивка

Spatial splits improve the rendering performance in scenes with a mix of large and small polygons. The downsides are longer BVH build times and slightly increased memory usage.

Use Curves BVH

Use a special type of BVH for rendering curves. The bounding boxes are not axis aligned allowing a spatially closer fit to the curve geometry. Disabling this option will reduce memory, at the cost of increasing curve render time.

BVH Time Steps

Split BVH primitives by this number of time steps to speed up render time at the expense of memory.

Use Compact BVH

Use a more compact BVH structure, which can reduce RAM usage but render slower.

Итоговая визуализация

Persistent Data

Keep render data in memory after rendering for faster re-renders and animation renders at the cost of extra memory usage while performing other tasks in Blender.

When using multiple View Layers, only data from a single view layer is preserved to keep memory usage within bounds; however, objects shared between view layers are preserved.

Viewport

Размер пикселя

Option to control the resolution for viewport rendering. Allows you to speed up viewport rendering, which is especially useful for displays with high DPI.
