Panel (Bảng)

Properties ‣ View Layer ‣ Freestyle

There is only one view map per view layer. It controls the edge detection parameters. Freestyle can be enabled/disabled per View Layer by toggling the checkbox in the panel header.

View Layer: Freestyle panel.

Chế độ điều khiển (Control Mode)

Which detected edges are actually rendered, and how, can be controlled either through:

Chế Độ Biên Soạn Tham Số (Parameter Editor Mode)

Lines are rendered via the parameter editor, easy but limited.

Chế Độ Tập Lệnh Python (Python Scripting Mode)

Lines are rendered via Python scripting, powerful but complex.

Bộ Đệm Nhớ Ánh Xạ Khung Nhìn (View Map Cache)

An option to reuse a previously computed view map for subsequent rendering. The cache is automatically updated when the mesh geometry of the input 3D scene has been changed.

This functionality offers a major performance boost for Freestyle animation rendering when the camera-space mesh geometry is static, as well as for repeated still renders with updates of line stylization options.

Although the ''View map cache'' checkbox is a view layer option, the cache memory is shared by all view layers and scenes. This means that if Freestyle is used for two or more view layers (possibly in different scenes through the Compositor), then the cached view map for one view layer is replaced by a new view map for another view layer and hence no performance gain is expected.

Thành Lượt Kết Xuất (As Render Pass)

Freestyle lines will not immediately be visible on top of the render image. Instead, Freestyle lines are rendered as a Render Pass which can be composited with the rendered image with an Alpha Over node.

Độ Mịn Bề Mặt (Face Smoothness)

Takes Smooth Shading into account for edges calculation.

Góc Độ Nếp Gấp (Crease Angle)

If two adjacent faces form an angle less than the defined Crease Angle, the edge between them will be rendered when using Crease edge type selection in a line set. The value also affects Silhouette edge type selection.

Loại Trừ (Culling)

Ignore the edges that are out of view. (Saves some processing time and memory, but may reduce the quality of the result in some cases.)

Advanced Options

Bán Kính Hình Cầu (Sphere Radius)

Affects the calculation of curvatures for Ridge, Valley and Suggestive Contour edge type selection in a line set. The curvature at each vertex is computed by averaging the shape of the surface within the specified radius. Increasing the value reduces noise and detail.

Đạo Hàm Kr Epsilon (Kr Derivative Epsilon)

Controls the threshold on the minimum rate of change of curvature used to filter the output of the Suggestive Contour edge type selection. Increasing the value reduces the amount of rendered lines, starting from smoother areas of the object (further information in this pdf).
