View Layer Properties

Panneau:Properties ‣ View Layer ‣ Freestyle

There is only one view map per view layer. It controls the edge detection parameters.

Mode Controle

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

Mode Parameter Editor
Lines are rendered via the parameter editor, easy but limited.
Mode Python Scripting
Lines are rendered via Python scripting, powerful but complex.
View Map Cache

Une option pour réutiliser une view map calculée antérieurement pour des rendus subséquents. Le cache est automatiquement mis à jour quand la géométrie de maillage de la scène 3D d’entrée a été modifiée.

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.

Face Smoothness
Takes Smooth Shading into account for edges calculation.
Crease Angle
Si deux faces adjacentes forment un angle inférieur au Crease Angle défini, l’arête entre elles sera rendue lors de l’utilisation de sélection de type d’arête Crease dans un line set. La valeur affecte aussi la sélection de type d’arête Silhouette.
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.)
Options avancées
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.
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).
