Specify locations for primitives and archive geometry

Specify the locations you want primitives or geometry to generate on your mesh surface using the Specify Points Tool.

1. Create a Description with Generate the Primitives set to At points you specify.

   Depending on whether you are creating a hair, fur or instanced geometry, see Create hair or fur using spline primitives or Instance primitives and archive geometry.

2. In the XGen window, click the Primitives tab.
3. In the Generator Attributes section, click Specify Points.

   The Specify Points Tool window appears. A circle icon replaces the cursor, which indicates that you can add points to this area of the geometry.

4. Do one of the following:
   • To use an existing points (.xuv) file, click Revert to Last Saved in the Specify Points Tool window.

     Maya loads the last points file that was created for the Description.

   • To create new point locations, click these areas of the polygon surface.

     Point markers appear at the specified locations. When the Description is previewed, primitives generate at the point locations.

     Note: To increase or decrease the radius of the Specify Points Tool, press the B key and drag your mouse.

   To delete a point location, + select its point marker.

5. (Optional) Make the point markers larger or smaller using Points Display Length.
6. Click Save and Close.

   Primitives display in the specified locations.
