## Options

### Offset

Parameter ID: `MDATA_SMOOTHSHIFT_OFFSET` · Range: [-∞..+∞m]

### Offset Variation

Parameter ID: `MDATA_SMOOTHSHIFT_VARIANCE` · Range: [0..+∞%]

Here you can change the offset of the extruded surfaces. You can also specify a **Offset Variation** value to vary the offset per smooth shift extrusion group.

### Preserve Groups

Parameter ID: `MDATA_SMOOTHSHIFT_PRESERVEGROUPS`

### Maximum Angle

Parameter ID: `MDATA_SMOOTHSHIFT_ANGLE` · Range: [0..180°]

This is the maximum angle at which surfaces may lie to each other to ensure that no additional surfaces are created with **Smooth Shift**. The Preserve Groups option can be used to enable or disable the entire fuctionality interactively.

The marked surfaces are those which had to be additionally built and inserted because the Maximum Angle was exceeded.

> **Tip:** Quadrangles (and, in some cases, triangles also) are inserted in these critical places where the angle is exceeded, ensuring that the surfaces are not torn apart. These triangles should be avoided if you want to use an object for Subdivision Surface, otherwise the Subdivision Surface object may display uneven shading properties.

### Subdivision

Parameter ID: `MDATA_SMOOTHSHIFT_SUBDIVISION` · Range: [1.00..+∞]

![Image: 003704.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/003704.jpg)\
Subdivision set to 1 (left) and 3 (right).

The **Subdivision** value defines the number of subdivisions along the smooth shift extrusion.

### Create N-gons

Parameter ID: `MDATA_SMOOTHSHIFT_CREATENGONS`

Enable this option if you have defined subdivisions but want to avoid the additional edges between the original polygons and the smooth shift extrusion that this would normally cause.
