EditGeo allows you to directly modify an object’s vertices or faces, depending on the Viewer selection mode currently active. You can also modify multiple objects simultaneously if the EditGeo is downstream of a MergeGeo node with multiple geometry inputs.
| 1. | Select the 3D object or MergeGeo you want to modify in the Node Graph. |
| 2. | Navigate to 3D > Modify > EditGeo to insert an EditGeo node. |
| 3. | In the node’s controls, use the display dropdown menu to select how you want to view your object in the Viewer while making changes to it. |
TIP: If you don’t have an image or texture associated with your geometry, you may find that enabling the headlamp control in the Viewer properties improves visibility.
Press S in the Viewer to display the Viewer properties, then enable the 3D > headlamp checkbox.
| 4. | Set the Viewer selection mode using the 3D selection tools in the top right corner of the Viewer: |
• Vertex selection - allows you to select individual vertices on geometry, giving you fine control while editing. You can also marquee select multiple vertices or use additive selection by holding down Shift.
• Face selection - allows you to select individual faces on geometry. You can also marquee select multiple faces or use additive selection by holding down Shift.
NOTE: You can turn off occlusion testing by clicking
the disable icon in the Viewer to allow you to select vertices and
faces that are hidden from the view point.
For example, selecting faces on the “front” of a cube with occlusion testing disabled also selects faces on the opposite, hidden side of the cube.
See 3D Selection Tools for more information.
| 5. | Set how the axis handles are aligned with your selection using the axis alignment dropdown: |
• object - the position of the xyz axis is determined by the average position of all vertices in the selection. The orientation of the axis is the same as the object's orientation.
• average normal - the position of the xyz axis is determined by the average position of all vertices in the selection. The orientation of the axis is aligned to the average of the current selection's normals.
In this mode, the z axis always points directly away from the current selection.
|
|
|
| Object alignment | Average normal alignment |
TIP: Holding Ctrl/Cmd+Alt allows you to drag the center of the axis across the surface of the geometry, with the orientation set to the nearest face's normal.
| 6. | Make vertex or face selections in the Viewer as required. Hold Shift to add to a selection or Alt+Shift to remove selections. |
| 7. | When you’re satisfied with your selections, drag the axis associated with the selection to a new position to edit the geometry. |
| 1. | Set the Viewer selection mode using the 3D selection tools in the top right corner of the Viewer: |
• Vertex selection - allows you to select individual vertices on geometry, giving you fine control while editing. You can also marquee select multiple vertices or use additive selection by holding down Shift.
• Face selection - allows you to select individual faces on geometry. You can also marquee select multiple faces or use additive selection by holding down Shift.
| 2. | Make selections in the Viewer and then click  in the properties panel. |
| 3. | Scrub the playhead to the required frame and transform the geometry using the handles in the Viewer. |
A keyframe is added automatically on the new frame.
| 4. | Repeat the process to produce the required animation. |
TIP: Click 
to remove a keyframe at the current frame.
| 5. | Click reset geometry to return the vertices to their original positions. |
