Environment Light COMP
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.
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.
dimmer - This parameter allows you to change the intensity of the light either as a static value or over time.
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 2D Type
envlightmaptype2d - ⊞ - Select the type of environment map to use (only equirectangular available for now).
equirect- Use equirectangular format for the environment map.
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 Rotate
envlightmaprotate - ⊞ - Rotate the texture specified by the Environment Map parameter above.
Use Pre-Filter Maps
envlightmapprefilter - ⊞ - Controls how the environment map is pre-filtered. A pre-filtered environment map is expensive to create, but results in much better rendering quality.
off- Disables pre-filtering the environment map. This is useful for animated environment maps, which can be far too expensive to pre-filter every frame. The rendering quality will be worse than when pre-filtering.
automatic- Pre-filter the environment map as needed. This results in the best rendering quality, but is quite expensive if the map changes.
- From Pre-Filter TOP
useprefiltertop- The output of the PreFilter Map TOP can be used instead, this allows for manually creating pre-filtered maps, including sequences of images for animated maps. The maps from the PreFilter Map TOP should be saved in a lossless format.
Pre-Filtered Specular Map
envlightspecmap - The 'Environment Light Specular Map' output from the PreFilter Map TOP to use.
Parameters - Render Page
The Display parameter page controls the component's material and rendering settings.
material - Selects a MAT to apply to the geometry inside.
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.
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.
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.
wcolor - ⊞ - Use the R, G, and B fields to set the Component's color when displayed in wireframe shading mode.
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.
reinitextensions - Recompile all extension objects. Normally extension objects are compiled only when they are referenced and their definitions have changed.
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:
Parameters - Common Page
The Common parameter page sets the component's node viewer and clone relationships.
parentshortcut - Specifies a name you can use anywhere inside the component as the path to that component. See Parent Shortcut.
opshortcut - Specifies a name you can use anywhere at all as the path to that component. See Global OP Shortcut.
Internal OP Shortcut 1
iopshortcut1 - Specifies a name you can use anywhere inside the component as a path to "Internal OP" below. See Internal Operators.
iop1 - The path to the Internal OP inside this component. See Internal Operators.
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.
opviewer - Select which operator's node viewer to use when the Node View parameter above is set to Operator Viewer.
Keep in Memory
keepmemory - Used only for Panel Components this keeps the panel in memory to it doesn't reload every time it is displayed.
enablecloning - Control if the OP should be actively cloned.
Enable Cloning Pulse
enablecloningpulse - Instantaneously clone the contents.
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.
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.
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
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.
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.
