Layout
Layout Orientation
Controls the overall position of parents and children:
Vertical Layout moves child nodes below their parents.
Horizontal Layout moves child nodes to the right of their parents.
Hierarchy Sorting
Sorts the root and child nodes according to one of the following criteria:
None (creation) does not sort the hierarchies at all. The default order is based on the order of creation of the root nodes.
by Type puts cameras first, followed by lights and then other 3D objects.
by Height/Width places the hierarchies in order of tallest to shortest. When two hierarchies have the same height, the one that is wider
is placed before the other.
by Width/Height places the hierarchies in order of widest to narrowest. When two hierarchies have the same width, the one that is taller
is placed before the other.
Clean Hierarchy
Controls whether nodes in the schematic view get rearranged when you change a hierarchy by parenting or cutting children.
If it is on, nodes in the affected hierarchy are automatically rearranged. The root of the hierarchy is not moved.
If it is off, nodes are not moved automatically.
Clean All
Controls whether nodes in the schematic view get rearranged when you display or hide different types of nodes using the options
in the Show menu or context menu.
If it is on, nodes are automatically rearranged when you display or hide different types of node. However, nodes are not moved
when you display or hide links.
If it is off, nodes are not moved automatically when you display or hide nodes and links.
Node Color
Sets the colors used to draw elements in the schematic:
Use Standard Colors displays unselected objects in black.
Use Wire Colors displays unselected objects using their wire color.
Use Diffuse Colors displays unselected objects using the diffuse component of their material. Objects without their own material inherit the
material of their parent or use the scene's default material.
Draw Parallel Links
Controls whether parent-child links are drawn as straight lines or as vertical and horizontal segments.
Show Grid
Displays a grid background on the schematic view.
Show Links for Selection Only
Displays links only for nodes that are selected. This simplifies the view because links aren't displayed for all objects at
once.
Show Icons
Displays icons for different element types, like in the explorer. Click an icon to open an element's property editor.
Visibility
Nodes
Models
Displays the roots of model hierarchies.
Simulation
Displays particle types and events.
Materials
Displays materials.
Node Sub-types
Lights
Displays lights.
Cameras
Displays cameras.
3D Geometry
Displays 3D objects with points, such as polygon meshes, NURBS surfaces, hair objects, point clouds, lattices, and so on.
Curves
Displays curve objects.
Nulls
Displays nulls.
Chains
Displays roots, bones, and effectors of kinematic chains.
Control Objects
Displays control objects like forces, waves, and volume deformers.
Texture Controls
Displays texture control objects.
Links
Shared Material
Displays links between objects and materials that have been applied to groups that contain those objects.
Constraint
Displays links between objects that are constrained and those they are constrained to.
Associated Model
Displays links between selective lights and any included or excluded objects, as well as between models and their instances.
Expression
Displays links between objects that have an expression on one of their transformation parameters and any objects involved
in the expression.
Operator
Displays links between objects that have an operator dependency, for example, between a lofted surface and the curves used
as inputs.
Simulation
Displays links between objects that are involved in a simulation, force example, between a force and any affected objects.
