StrandOrientation

 
 
 

Used to orient shapes along a strand.

If StrandDeform is false, the orientation is relative to the point cloud's local space. If StrandOrientation is not defined, the base particle's Orientation is used instead.

If StrandDeform is true, StrandOrientation provides an extra rotation that is applied on top of the orientation defined by the strand's tangent and StrandUpVector. The reference for StrandOrientation is established by using the strand's tangent as the Y axis and StrandUpVector as the X axis. If StrandUpVector is not defined, the up-vector is calculated from the camera, which will make the deformations rotate if the camera moves.

If the size of this array does not match StrandPosition, it is ignored.
