This section describes the different ways in which you can navigate in the render tree workspace, rearrange nodes, snap nodes to a grid, frame nodes, and update or clear the workspace.
The render tree uses the same navigation controls as other views in Softimage:
Scroll the mouse wheel to zoom, if it is enabled in your preferences.
You can also use the Bird's Eye View to quickly move to a specific part of the tree.
Press the Z key to activate the Pan and Zoom tool.
Press the S key to activate the Navigation tool:
These tools are also available from the Tools menu in the render tree toolbar.
Press Shift+Z to activate the Rectangular Zoom tool. This tool is also available from the Tools menu.
By default, you can zoom using the mouse wheel:
Press Ctrl to zoom quickly, Shift to zoom slowly, and Ctrl+Shift to zoom even more slowly.
If you like, you can disable the mouse wheel zoom or restrict it to the Navigation tool so that you can use the mouse wheel with other tools. See Mouse Wheel in Camera Preferences [Preference Reference].
The bird's-eye view is a miniature "map" of your ICE tree in the upper-right corner of the render tree workspace. You can use it to quickly move to parts of a render tree that are too large to display in the available work area.
To toggle this view on or off, choose Show Bird's Eye View.
Use the bird's eye view to quickly move about your tree. The extent of the current display is shown as a white outline. Small gray rectangles correspond to the shader nodes in the render tree.
Click anywhere in the bird's eye view to jump to the corresponding area of the tree.
Framing Nodes in the Render Tree
You can frame the entire render tree, a selected node, or a selected branch.

Rearranging Nodes in the Workspace
As you work with a render tree and move nodes around, you'll probably want to clean up the workspace from time to time. You can position each node individually, or you can simply use the rearrange command. Rearrange places every node in an orderly and logical manner without any overlapping.
To automatically arrange nodes
Select the nodes to rearrange, or deselect all nodes if you want to arrange the entire tree.
Press Ctrl+R, or choose Tools Rearrange.
Alternatively, you can right-click an empty area of the render tree workspace and choose Rearrange from the menu.
When working with a large and complex render tree, it may not take too long for nodes to start overlapping and cluttering the workspace. You can rearrange the nodes by having them snap to the grid that covers the render tree work area.
Right-click an empty area of the render tree workspace to open a contextual menu, or click Tools in the render tree command bar to open the Tools menu.
From either menu, choose one of the following:
By default, all unconnected shader nodes are always left in the render tree for an object. This is often useful for keeping shaders around when you're trying out different shader connections.
However, if you want to clean up the render tree workspace, you can delete all shader nodes that are not currently connected to the Material node.
