Hiệu Suất Thi Hành (Performance)#
Tham Chiếu (Reference)
- Panel (Bảng):
Properties that affect render speeds or memory consumption. There are several presets available to help choose between different trade offs:
- Mặc Định (Default):
Cân bằng giữa việc tiết kiệm bộ nhớ và các cài đặt kết xuất nhanh hơn.
- Kết Xuất Nhanh Hơn (Faster Render):
Uses settings to render faster at the cost of higher memory consumption.
- Bộ Nhớ Ít Hơn (Lower Memory):
Sử dụng các cài đặt để giảm bộ nhớ, đồng thời xem xét đến hao tổn của các kết xuất chậm hơn.
Số Luồng (Threads)#
- Chế Độ Đa Luồng (Threads Mode)
Method to determine the maximum number of CPU cores to use while rendering.
- Tự Động Phát Hiện (Auto-Detect):
Automatically chooses the amount of threads to match the number of logical processors on your computer.
- Cố Định (Fixed):
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.
- Số Luồng (Threads)
The maximum number of CPU cores to use simultaneously while rendering.
Số Ô (Tiles)#
- Sử Dụng Phân Ô (Use Tiling)
Render high resolution images in tiles to reduce memory usage. Tiles are cached to disk while rendering to save memory.
- Kích Thước Ô (Tile Size)
This value is used to control the size of the tile used for rendering; decreasing the size reduces memory usage.
Ghi chú
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.
Cấu Trúc Tăng Tốc (Acceleration Structure)#
- Sử Dụng Phân Tách Không Gian (Use Spatial Splits)
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.
- Sử Dụng BVH cho Đường Cong (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.
- Bước Thời Gian của BVH (BVH Time Steps)
Split BVH primitives by this number of time steps to speed up render time at the expense of memory.
- Sử Dụng BVH Gọn Nhẹ (Use Compact BVH)
Use a more compact BVH structure, which can reduce RAM usage but render slower.
Kết Xuất Kết Thúc (Final Render)#
- Dữ Liệu Ổn Định (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.
Cổng Nhìn (Viewport)#
- Kích Thước Điểm Ảnh (Pixel Size)
Option to control the resolution for viewport rendering. Allows you to speed up viewport rendering, which is especially useful for displays with high DPI.
