This parameter set is only available for the → “Spline” emitter. It offers various options to customize the emitter's viewport representation. In order to change the different states of visibility please activate the “EDIT” mode under Node Params > Spline Emitter > EDIT.
Show CP
“CP” stands for “control point” and with this option you can switch them off or on. Control vertices are displayed as small yellow squares.
Show CP indexes
Every control point has an index number which can be shown in the viewport.
Show intermediate points
Splines are subdivided into a certain number of intermediate points – these points cannot be edited. In “Adaptive” mode the distance between the intermediate points depends on the spline's curvature.
Show hull
The spline's hull is created from the connection of the control points' tangent handles. When “Show hull” is active the hull's control points can be edited and moved (R) to change the spline's curvature. To do this, please make sure that “Show handles” is enabled.
Show handles
If you want to show or hide the control vertices' tangent handles please toggle this checkbox.
