Summary

The Environment Light Component controls the color and intensity of an environmental light in a given scene. This light, unlike the Light Component, has no particular position. It comes from outside all of the objects in the scene and lights them. The orientation of the objects and the Environment Light Map will affect how each side of the objects is lit. However the position of the objects in space will have no effect on how the environment light hits them.

Parameters - Light Page

You can modify the color of the light three ways: Color List, Hue, Saturation, and Value, or Red, Green, and Blue. To choose one, click on the appropriate box and the color editing fields below change accordingly.

Light Color c - You can modify the color of the light three ways: Color List, Hue, Saturation, and Value, or Red, Green, and Blue. To choose one, click on the appropriate box and the color editing fields below change accordingly.

  • Red cr -
  • Green cg -
  • Blue cb -

Dimmer dimmer - This parameter allows you to change the intensity of the light either as a static value or over time.  

Environment Map envlightmap - Uses a TOP texture to define an environment map for the material. Environment mapping simulates an object reflecting its surroundings. The TOP defined in this parameter is the texture that will be reflected. The Env Map is added to whatever the normal lighting will be, so to make an object purely reflective turn the Diffuse and Specular parameters to 0. This input expects a sphere map. An example of a sphere map can be found here. This input will also accept a cube map, created with the Cube Map TOP or the Render TOP's Render Cube Map parameter.

Parameters - Extensions Page

The Extensions parameter page sets the component's python extensions. Please see extensions for more information.

Extension Object 1 extension1 - A number of class instances that can be attached to the component.

Extension Name 1 extname1 - Optional name to search by, instead of the instance class name.

Promote Extension 1 promoteextension1 - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Extension Object 2 extension2 - A number of class instances that can be attached to the component.

Extension Name 2 extname2 - Optional name to search by, instead of the instance class name.

Promote Extension 2 promoteextension2 - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Extension Object 3 extension3 - A number of class instances that can be attached to the component.

Extension Name 3 extname3 - Optional name to search by, instead of the instance class name.

Promote Extension 3 promoteextension3 - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Extension Object 4 extension4 - A number of class instances that can be attached to the component.

Extension Name 4 extname4 - Optional name to search by, instead of the instance class name.

Promote Extension 4 promoteextension4 - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Re-Init Extensions reinitextensions - Recompile all extension objects. Normally extension objects are compiled only when they are referenced and their definitions have changed.


Parameters - Common Page

The Common parameter page sets the component's node viewer, clone relationships, Parent Shortcut, and Global OP Shortcut.

Parent Shortcut parentshortcut - Specifies a name you can use anywhere inside the component as the path to that component. See Parent Shortcut.

Global OP Shortcut opshortcut - Specifies a name you can use anywhere at all as the path to that component. See Global OP Shortcut.

Node View nodeview - - Determines what is displayed in the node viewer, also known as the Node Viewer. Some options will not be available depending on the Component type (Object Component, Panel Component, Misc.)

  • Default Viewer default - Displays the default viewer for the component type, a 3D Viewer for Object COMPS and a Control Panel Viewer for Panel COMPs.
  • Operator Viewer opviewer - Displays the node viewer from any operator specified in the Operator Viewer parameter below.

Operator Viewer opviewer - Select which operator's node viewer to use when the Node View parameter above is set to Operator Viewer.

Keep in Memory keepmemory -

Enable Cloning enablecloning - Control if the OP should be actively cloned. The Pulse button can be used to instantaneously clone the contents.

Enable Cloning Pulse enablecloningpulse -

Clone Master clone - Path to a component used as the Master Clone.

Load on Demand loadondemand - Loads the component into memory only when required. Good to use for components that are not always used in the project.

External .tox externaltox - Path to a .tox file on disk which will source the component's contents upon start of a .toe. This allows for components to contain networks that can be updated independently. If the .tox file can not be found, whatever the .toe file was saved with will be loaded.

Reload .tox on Start reloadtoxonstart - When on (default), the external .tox file will be loaded when the .toe starts and the contents of the COMP will match that of the external .tox. This can be turned off to avoid loading from the referenced external .tox on startup if desired (the contents of the COMP are instead loaded from the .toe file). Useful if you wish to have a COMP reference an external .tox but not always load from it unless you specifically push the Re-Init Network parameter button.

Save Backup of External savebackup - When this checkbox is enabled, a backup copy of the component specified by the External .tox parameter is saved in the .toe file. This backup copy will be used if the External .tox can not be found. This may happen if the .tox was renamed, deleted, or the .toe file is running on another computer that is missing component media.

Sub-Component to Load subcompname - When loading from an External .tox file, this option allows you to reach into the .tox and pull out a COMP and make that the top-level COMP, ignoring everything else in the file (except for the contents of that COMP). For example if a .tox file named project1.tox contains project1/geo1, putting geo1 as the Sub-Component to Load, will result in geo1 being loaded in place of the current COMP. If this parameter is blank, it just loads the .tox file normally using the top level COMP in the file.

Re-Init Network reinitnet - This button will re-load from the external .tox file (if present), followed by re-initializing itself from its master, if it's a clone.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Path.

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

Operators that have 1 or more input, like a Math CHOP, are called filters. See Generator.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.

Any component can be extended with its own Python classes which contain python functions and data.

The component types that are used to render 3D scenes: Geometry Component contain the 3D shapes to render, plus Camera, Light, Ambient Light, Null, Bone, Handle and other component types.

A Parent Shortcut is a parameter on a component that contains a name that you can use anywhere inside the component to refer to that component using the syntax parent.Name, for example parent.Effect.par.w to obtain panel width.

A name for a component that is accessible from any node in a project, which can be declared in a component's Global Operator Shortcut parameter.

The viewer of a node can be (1) the interior of a node (the Node Viewer), (2) a floating window (RMB->View... on node), or (3) a Pane that graphically shows the results of an operator.

A custom interactive control panel built within TouchDesigner. Panels are created using Panel Components whose look is created entirely with TOPs.

To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately. A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel, and a pulse via python is via a .pulse() call on a pulse-type parameter, such as Reset in a Speed CHOP.

Cloning can make multiple components match the contents of a master component. A Component whose Clone parameter is set will be forced to contain the same nodes, wiring and parameters as its master component. Cloning does not create new components as does the Replicator COMP.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called Root. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

TouchDesigner Component file, the file type used to save a Component from TouchDesigner.

TOuch Environment file, the file type used by TouchDesigner to save your project.

An Operator Family that contains its own Network inside. There are twelve 3D Object Component and eight 2D Panel Component types. See also Path.

Every component contains a network of operators that create and modify data. The operators are connected by wires that define where data is routed after the operator cooks its inputs and generates an output.
