The following page provides information on the plugininfo tool.
## **Overview**
---
The plugininfo tool generates documentation for all V-Ray plugins. It can be used to list all V-Ray plugins or to display a detailed information for a specific one by using the commands from the **Options** table.
Note that plugininfo displays only core V-Ray plugin parameters. User data parameters are not listed.
*User data* parameters are employed in the communication between V-Ray for Rhino and its UI, whereas the actual scene parameters (V-ray core) are set accordingly only at render time.
The precise names of such *user data *parameters can be found in exported V-Ray files:
- for Settings - export a .*vropt* file
- for Assets - export an asset of the required type as a .*vrmat* file
Their parameter handlers contain `isUserData="1"`
## **Usage**
---
To run the plugininfo tool, its active directory needs to be changed to the V-Ray bin directory. A simple way to do it is by running the following line in command prompt:
```
cd "C:\Program Files\Chaos\V-Ray\V-Ray for Rhinoceros\vrayappsdk\bin" && "C:\Program Files\Chaos\V-Ray\V-Ray for Rhinoceros\vrayappsdk\bin\plugininfo.exe"
```
The tool's options can be accessed using the following syntax:
**plugininfo [ options ] -list [ ]**
Lists all V-Ray plugins.
When is given, only plugins that match the given name are printed. Note that the wildcard symbol '*' is supported.
**plugininfo [ options ] **
Displays detailed description for the specified plugin - plugin id, location, supported interfaces, parameters, their types, default values, description, and optional ui guides in the following format:
: /* */ { }
### **Options**
---
| **Option** | **Description** |
| --- | --- |
| **-plugindir ** | Passes plugin search directory. If not specified, the directory './plugins' is used by default.
More than one directory can be specified, separated by '**;**' (on Windows) or '**:**' (on Linux). The [environment variable](https://docs-chaos.atlassian.net/wiki/spaces/VNS/pages/115605616) VRAY_PLUGINS_x64 can be used to specify additional plugin paths. |
| **-listByCategory** | Lists plugins by categories. |
| **-pluginInterface ** | Processes plugins that support only specified interface. Valid interface names are:
EXT_BITMAP, EXT_BSDF, EXT_GEOM_GEN, EXT_GEOM_PARTICLE_DATA, EXT_LIGHT,
EXT_LIGHT_LINKER, EXT_LIGHT_LIST, EXT_MAPPED_SURFACE, EXT_MATERIAL,
EXT_REFERENCED_SURFACE, EXT_RENDER_CHANNEL, EXT_RENDER_VIEW, EXT_STATIC_GEOM_SOURCE,
EXT_TEXTURE, EXT_TEXTURE_FLOAT, EXT_TEXTURE_INT, EXT_TEXTURE_MATRIX,
EXT_TEXTURE_TRANSFORM, EXT_TEXTURE_VECTOR, EXT_UVWGEN, EXT_VOLUMETRIC,
EXT_VRAY_PER_PARTICLE_DATA |
| **-json** | Displays plugin description in JSON format. If plugin name is given, only formatting for that plugin is generated; otherwise all plugins are formatted. When -outputDir is given, JSON formatting for each plugin is saved in a separate file in that directory. The file should be saved as '.json', otherwise output is passed to the standard output. |
| **-html** | Generates HTML documentation. |
| **-htmlOutput|-outputDir
