Hosts are entities on which thousands of instances will be scattered. They can either be , or .

Surface hosts

A surface host is an entity that contains faces on which instances will be scattered.

To add new surface hosts, click the icon and pick groups or components in the model. When you're happy with your selection, click anywhere in Skatter's interface to stop picking hosts.

Texture coordinates

If the geometry of the surface host already has texture coordinates (coming from another 3D package or authored via another SketchUp extension), then one of the Input modes can be selected.

Otherwise, Skatter can generate new texture coordinates with other modes that match various shapes.

Texture coordinates
When to use

Input - Front

Geometry already has texture coordinates on its front faces

Input - Back

Geometry already has texture coordinates on its back faces

XY plane

Flat geometry roughly aligned with the XY plane

YZ plane

Flat geometry roughly aligned with the YZ plane

XZ sphere

Flat geometry roughly aligned with the XZ plane

Sphere

Sphere-like geometry

Cube

Cube-like geometry

Automatic

More complex geometry (this feature is experimental, results may vary)

SketchUp only allows extensions to draw textures in the viewport since SketchUp 2020 so the preview of texture coordinates is not available for older versions.

Curve hosts

A curve host is an entity that contains edges on which instances will be scattered.

Aligning instances

Curve hosts have an Align instance axis with curve parameter to adjust the orientation of scattered instances. When enabled, each instance will be rotated so that the selected local axis of the object points in the same direction as the curve host.

Point sets

A point set is a collection of positions that you can pick manually.

Converting existing objects into a Point set

It is possible to convert existing SketchUp objects into a Point set host. Select the objects in SketchUp, then right-click and choose Skatter > Convert to composition.

Each selected object will turn into an instance and will retain its position, orientation, and material. However, you can now apply Skatter's masks, filters, and transformations to them.

Another way to pick several surface hosts is to first select them in SketchUp and then click the icon while pressing the Shift key.

Surface hosts have a Texture coordinates parameter that interacts with .

To add new curve hosts, click the icon and pick groups or components in the model. When you're happy with your selection, click anywhere in Skatter's interface to stop picking hosts.

Another way to pick several curve hosts is to first select them in SketchUp and then click the icon while pressing the Shift key (see above for an illustration with surfaces.

To add a new point set, click the icon and start placing points. Click anywhere in the Skatter interface to stop creating points. You can then click the icon at any point to add new points to existing point sets.

To erase points, click the icon and select the points to remove.

When placed on a surface, points are oriented according to the face normals. You can tune this behavior with the parameter of the composition.
