Environment Light COMP

From TouchDesigner 099 Wiki


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

Light Color cr cg cb - 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.

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.

Environment Map Quality envlightmapquality - Controls the number of samples used by the Environment Light which determines the quality of the result. This value is multiplied by the PBR MATs Env Light Quality parameter.

Environment Map Color envlightmapcolor[rgb] - This color is multiplied with the texture specified by the Environment Map parameter above.

Environment Map Rotate envlightmaprotate[xyz] - Rotate the texture specified by the Environment Map parameter above.

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 (on top of) larger values.

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

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 - 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 - Displays the default viewer for the component type, a 3D Viewer for Object COMPS and a Control Panel Viewer for Panel COMPs.
  • Operator Viewer - 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 cloned. The Pulse button can be used to 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.

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.
