Hosts
Hosts are entities on which thousands of instances will be scattered. They can either be surfaces, curves or point sets.
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.
Another way to pick several surface hosts is to first select them in SketchUp and then click the icon while pressing the Shift key.
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.
A curve host is an entity that contains edges on which instances will be scattered.
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.
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.
A point set is a collection of positions that you can pick manually.
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 Pointing parameter of the composition.
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.
