Ambient Light COMP

Summary

The Ambient Light Component controls the color and intensity of the environmental light in a given scene. This light, unlike the Light Component, has no particular source. The light it sheds comes from everywhere as opposed to a point light source or focused spotlight.

Parameters - Light Page

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.


Parameters - Render Page

The Display parameter page controls the component's material and rendering settings.

Material material - Selects a MAT to apply to the geometry inside.

Render render - Whether the Component's geometry is visible in the Render TOP. This parameter works in conjunction (logical AND) with the Component's Render Flag.

Draw Priority drawpriority - Determines the order in which the Components are drawn. Smaller values get drawn after larger values. The value is compared with other Components in the same parent Component, or if the Component is the top level one listed in the Render TOP's 'Geometry' parameter, then against other top-level Components listed there. This value is most often used to help with Transparency.

Pick Priority pickpriority - When using a Render Pick CHOP or a Render Pick DAT, there is an option to have a 'Search Area'. If multiple objects are found within the search area, the pick priority can be used to select one object over another. A higher value will get picked over a lower value. This does not affect draw order, or objects that are drawn over each other on the same pixel. Only one will be visible for a pick per pixel.

Wireframe Color wcolor - - Use the R, G, and B fields to set the Component's color when displayed in wireframe shading mode.

  • Red wcolorr -
  • Green wcolorg -
  • Blue wcolorb -

Light Mask lightmask - By default all lights used in the Render TOP will affect geometry renderer. This parameter can be used to specify a sub-set of lights to be used for this particular geometry. The lights must be listed in the Render TOP as well as this parameter to be used.


Parameters - Extensions Page

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

Object ext0object - A number of class instances that can be attached to the component.

Name ext0name - Optional name to search by, instead of the instance class name.

Promote ext0promote - 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 and clone relationships.

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.

Shortcut iop0shortcut - Specifies a name you can use anywhere inside the component as a path to "Internal OP" below. See Internal Operators.

OP iop0op - The path to the Internal OP inside this component. See Internal Operators.

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.

Enable Cloning enablecloning - Control if the OP should be actively cloneing. Turning this off causes this node to stop cloning it's 'Clone Master'.

Enable Cloning Pulse enablecloningpulse - Instantaneously clone the contents.

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.

Enable External .tox enableexternaltox - 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.

Enable External .tox Pulse enableexternaltoxpulse - This button will re-load from the external .tox file (if present).

External .tox Path 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 Custom Parameters reloadcustom - When this checkbox is enabled, the values of the component's Custom Parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

Reload Built-In Parameters reloadbuiltin - When this checkbox is enabled, the values of the component's built-in parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

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.

Relative File Path Behavior relpath - - Set whether the child file paths within this COMP are relative to the .toe itself or the .tox, or inherit from parent.

  • Use Parent's Behavior inherit - Inherit setting from parent.
  • Relative to Project File (.toe) project - The path, when specified as a relative path, will be relative to the .toe file.
  • Relative to External COMP File (.tox) externaltox - The path, when specified as a relative path, will be relative to the .tox file. When no external COMP file is specified, or when Enable External .tox is not toggled on, this doesn't have any impact.


Info CHOP Channels

Extra Information for the Ambient Light COMP can be accessed via an Info CHOP.

Common COMP Info Channels

  • num_children - Number of children in this component.

Common Operator Info Channels

  • total_cooks - Number of times the operator has cooked since the process started.
  • cook_time - Duration of the last cook in milliseconds.
  • cook_frame - Frame number when this operator was last cooked relative to the component timeline.
  • cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.
  • cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.
  • cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.
  • cooked_this_frame - 1 if operator was cooked this frame.
  • warnings - Number of warnings in this operator if any.
  • errors - Number of errors in this operator if any.
