Replaces the "self" Topology with an extrusion based on the strands of a point cloud. The number of segments in the extrusion is the same as the number of segments in the strand. The size of the cross-section is modulated by the particles' StrandSize attribute. See Creating an Extrusion Along Strands.
Specify an attribute name to store an integer that you can use to differentiate the vertices extruded along different strands.
Enable Auto UVs |
Creates an attribute based on the extrusion that you can use as texture UV coordinates. |
Reference |
Specify the name of the attribute to use. |
U/V Start/End |
Use these controls to limit the texture coordinates of the caps to a specific section of UV space. This has the effect of scaling the texture on the caps. To control the projection along the extrusion, use the Repeat controls on the Advanced tab of the Image shader in the render tree. |
Mute Deformation |
Creates the geometry and other attributes but does not deform it along the strand. This allows you to create the geometry in one tree, and deform it along the strand in another tree higher up in the construction stack using Deform Strand Extrusion. When this option is on, the Base Up Vector settings in this compound have no effect. Use the equivalent settings in Deform Strand Extrusion. |
Remove Strand Position |
Ignores the specified elements in the StrandPosition array. This is useful when using strand compounds that set StrandPosition[0] to the particles' PointPosition. If Mute Deformation is on, this option should be set to the same value here and in Deform Strand Extrusion. |
Index |
The index in the Strand Position array to ignore. If Mute Deformation is on, this option should be set to the same value here and in Deform Strand Extrusion. |
