class bpy.types.CyclesCurveRenderSettings(PropertyGroup)

encasing_ratio

Scale factor for encasing strand width

Type :float in [0, 100], default 1.01

interpolation

Interpolation method

• LINEAR Linear interpolation, Use Linear interpolation between segments.
• CARDINAL Cardinal interpolation, Use cardinal interpolation between segments.
• BSPLINE B-spline interpolation, Use b-spline interpolation between segments.

Type :enum in [‘LINEAR’, ‘CARDINAL’, ‘BSPLINE’], default ‘BSPLINE’

line_method

Method for line segment intersection

• ACCURATE Accurate, Always take into consideration strand width for intersections.
• QT_CORRECTED Corrected, Ignore width for initial intersection and correct later.
• ENDCORRECTED Correct found, Ignore width for all intersections and only correct closest.
• QT_UNCORRECTED Uncorrected, Calculate intersections without considering width.

Type :enum in [‘ACCURATE’, ‘QT_CORRECTED’, ‘ENDCORRECTED’, ‘QT_UNCORRECTED’], default ‘ACCURATE’

normalmix

Scale factor for tangent normal removal (zero gives ray normal)

Type :float in [0, 2], default 1.0

preset

Hair rendering mode

• CUSTOM Custom, Set general parameters.
• TANGENT_SHADING Tangent Normal, Use planar geometry and tangent normals.
• TRUE_NORMAL True Normal, Use true normals (good for thin strands).
• ACCURATE_PRESET Accurate, Use best settings (suitable for glass materials).

Type :enum in [‘CUSTOM’, ‘TANGENT_SHADING’, ‘TRUE_NORMAL’, ‘ACCURATE_PRESET’], default ‘TRUE_NORMAL’

primitive

Type of primitive used for hair rendering

• TRIANGLES Triangles, Create triangle geometry around strands.
• LINE_SEGMENTS Line Segments, Use line segment primitives.
• CURVE_SEGMENTS ?Curve Segments?, Use curve segment primitives (not implemented).

Type :enum in [‘TRIANGLES’, ‘LINE_SEGMENTS’, ‘CURVE_SEGMENTS’], default ‘LINE_SEGMENTS’

resolution

Resolution of generated mesh

Type :int in [3, 64], default 3

segments

Number of segments between path keys (note that this combines with the ‘draw step’ value)

Type :int in [1, 64], default 1

triangle_method

Method for creating triangle geometry

• CAMERA Planes, Create individual triangles forming planes that face camera.
• RIBBONS Ribbons, Create individual triangles forming ribbon.
• TESSELLATED Tessellated, Create mesh surrounding each strand.

Type :enum in [‘CAMERA’, ‘RIBBONS’, ‘TESSELLATED’], default ‘CAMERA’

use_backfacing

Test back-faces of strands

Type :boolean, default False

use_cache

Type :boolean, default True

use_curves

Activate Cycles hair rendering for particle system

Type :boolean, default True

use_encasing

Ignore strands encasing a ray’s initial location

Type :boolean, default True

use_joined

Fill gaps between segments (requires more memory)

Type :boolean, default False

use_parents

Use parents with children

Type :boolean, default False

use_smooth

Use vertex normals

Type :boolean, default True

use_tangent_normal

Use the tangent normal for all normals

Type :boolean, default False

use_tangent_normal_correction

Correct the tangent normal for the strand’s slope

Type :boolean, default False

use_tangent_normal_geometry

Use the tangent normal for actual normal

Type :boolean, default False
