 +====== Generator Editor ======
 +
 +The Generation Editor is the area where models are constructed at the highest conceptual level. [[kcgenerators|Generators]] are added to represent the branches, roots, fronds, leaves, and every other component of a tree. The structure of a tree is defined by how the generators are linked. The following image shows a notional tree model and the generator hierarchy used to make it.

 +
 +===== Adding Generators =====
 +Creating and managing the generator hierarchy is the most fundamental task of the Generation Editor. ​ The following generators are available to use:
 +
 +{{ ::​all_generators.jpg?​nolink |}}
 +
 +^Tree|Root of the hierarchy and houses global model properties (cannot be added, deleted, or moved).|
 +^[[branch_generator|Branch]]|Creates polygonal and subdivision branches.|
 +^Cap|Caps off the end or beginning of open branches.|
 +^Shell|Puts a whole or partial shell around a branch (this is a special mode of the Branch generator).|
 +^[[knot_generator|Knot]]|Adds knots, cavities, gashes, and lumps to branch geometry.|
 +^[[fin_generator|Fin]]|Adds small, planar details like fungi and peeling bark to branches.|
 +^[[leaf_mesh_generator|LeafMesh]]|Creates mesh based leaf geometry.|
 +^[[batchedleaf_generator|BatchedLeaf]]|Very efficiently creates mesh-based leaf geometry (but you can't node edit the results!).|
 +^[[frond_generator|Frond]]|Places blade or mesh geometry along a branch.|
 +^[[zone_generator|Zone]]|Grow geometry from a mesh or circular region.|
 +
 +Now, let's take a look at the three main ways to add a new generator:
 +
 +  - Click the Add icon in the Generation Editor toolbar.
 +  - Right-click a generator and select an option from the "Add geometry to selected"​ menu.
 +  - Click the Add icon in the [[tooltree_window|Tree Window]] toolbar.
 +
 +All three of these options bring up the same menu of options to add. Each entry is one of a series of templates designed to look like common vegetation components. ​ Each template is one or more of the generators listed above, with its properties set to commonly used values. ​ For example, when you add "​Trunk"​ geometry a [[branch_generator|Branch]] generator is added with values already set to look like a typical trunk.
 +
 +>​**Note:​** You can use the Default Generator submenu to add a single generator of any type and modify it as you see fit.
 +
 +When any of these methods are used to add a generator, the new generator is placed in one of two locations in the hierarchy:
 +
 +  * If nothing is selected, the new generator will be made a child of the Tree Generator.
 +  * If a generator is selected, the new generator will be made a child of that generator.
 +
 +>​**Note:​** The Tree generator is always present and cannot be deleted or moved. ​ It acts as the root of the hierarchy and houses many of the global model properties.
 +
 +The fourth way to add a new generator is to copy an existing generator and then paste it.  Generators placed this way will not be in the hierarchy until you explicitly link them.
 +
 +>​**Note:​** Any generator that cannot trace links back to the Tree generator will be ignored and will not affect the model in any way.
 +
 +Select a generator and press "​F2"​ to rename it.
 +
 +===== Linking Generators =====
 +Generators are linked together in a hierarchy that represents the anatomical structure of the model. ​ Each generator can have exactly one parent and each generator can have multiple children. ​ Here are the two ways to create a link between generators:
 +
 +  * Add a new generator via the three main ways listed in the previous section. ​ When you do, a link is automatically created.
 +  * Drag a generator and drop it on another one.  When you do this, any old link is deleted and the new one is created.
 +
 +To delete a link, select it and press the Delete key.
 +
 +===== Icon Overlays =====
 +Generators and links will frequently have context-sensitive hint icons applied to them.  Consult the image below and the following list for a description of what the icons mean.
 +
 +{{ ::​icon_overlays.jpg?​nolink |}}
 +
 +  * **A - Messages:** Indicates that at least one error, warning, or note messages is available for this generator. ​ Messages can be viewed by selecting the generator and opening the message pane on the [[toolpropertybar|Property Bar]].
 +  * **B - Selection Tag:** Indicates that a scene object that concerns the generator is selected (usually a force that is used on the generator or a node created by the generator).
 +  * **C - Hand Drawing:** Indicates that the generator is hand drawn.
 +  * **D - Node Count:** Relays the number of nodes made by the link.  In this example, there are 555 frond nodes.
 +  * **E - Hidden Generator:​** Hidden generators are slightly grayed out.
 +  * **F - Shape Control:** Generators under shape control are indicated by the blue highlight.
 +
 +>​**Note:​** The "​Forces"​ and "Mesh Forces"​ icons near the Tree generator provide quick access to force selection and creation.
 +
 +===== Toolbar =====
 +The Generation Editor toolbar offers three options, Add, Action and Randomize:
 +
 +==== Add ====
 +Use this button to add generators as described above.
 +
 +==== Actions ====
 +This button is the same as the right-click menu and changes based on whether something is selected or not.
 +
 +If nothing is selected:
 +
 +  * **Add geometry:** Add generators as described above.
 +  * **Organize:​** Automatically arrange generators and control whether the generators are displayed in portrait or landscape mode.
 +  * **Zoom all:** Zoom out to see all of the generators (double clicking empty space is a shortcut for this operation).
 +  * **Paste:** Pastes and copied generators.
 +
 +If a generator is selected:
 +
 +  * **Add geometry to selected:** Adds generators as described above.
 +  * **Save selected as template...:​** Saves any generator arrangement you make as a template and uses it later via the "From file..."​ option on the add menu.
 +  * **Organize:​** Automatically arranges generators and controls whether the generators are displayed in portrait or landscape mode.
 +  * **Zoom all:** Zooms out to see all of the generators (double clicking empty space is a shortcut for this operation).
 +  * **Hand drawing:** Converts procedural generators to hand-drawn generators where applicable and assigns [[kchanddrawing|hand drawing]] targets and lock states.
 +  * **Toggle visibility:​** Shows/Hides selected generators. ​ Hidden generators will still compute if any of their descendants are visible.
 +  * **Clear node edits:** Removes any node edits made to the nodes created by this generator. ​ It does not affect deleted nodes (unlink and relink the generator to bring back all deleted nodes).
 +  * **Select nodes with edits:** Switches to [[kcgenerators_vs._nodes|node editing mode]] and selects all of the nodes that have been node edited. ​
 +  * **Select and reveal hidden nodes:** Switches to node editing mode and ensures all of the nodes are no longer hidden. ​ Any that were hidden will now be selected.
 +  * **Randomize selected:** Randomizes only the selected generators. ​ You'll need [[toolvariance_editor|variance]] on some properties for this to work!
 +  * **Variance:​** Quickly clears all variances or quickly sets all of their types to the same thing.
 +  * **Select:** Quickly selects all generators of the same type currently selected. ​ This is useful to make broad changes like making all of the leaves bigger.
 +  * **Cut:** Copies a generator to the buffer and delete it.
 +  * **Copy:** Copies a generator to the buffer.
 +  * **Paste:** Pastes the contents of the buffer (new generators are created).
 +  * **Paste into:** Pastes the contents of the buffer into the selected generator (no new generators created).
 +  * **Duplicate:​** Instantly makes a copy of the selected generator(s).
 +  * **Rename:** Pops up a dialog box where you can type in a new name for the generator.
 +  * **Delete:** Deletes the currently selected generators and links.
 +
 +==== Randomize ====
 +Randomizes the whole model if no generators are selected or only the selected generators otherwise. ​ You'll need [[toolvariance_editor|variance]] on some properties for this to work!
