This page provides information on exploring the parameters of materials and textures created from plugins with V-Ray.

 

## **Overview**

---

Materials and textures can be created from any V-Ray Standalone material or texture plugin that comes with the V-Ray installation. The parameters of these materials and textures can be accessed through the command prompt.

There are two separate tools that contain the above information: **plgparams.exe** and <span style="color: #172b4d">**plugininfo.exe**</span><span style="color: #172b4d">.</span>


## **Location**

---

By default, the **plgparams.exe** can be found in:

***C:\Program Files\Chaos\V-Ray\3ds Max 20xx\bin\*** for V-Ray for 3ds Max 2021 and earlier, or

***C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax20xx\bin **** *for V-Ray for 3ds Max 2022 and later.


By default, the **plugininfo.exe** can be found in:

***C:\Program Files\Chaos\V-Ray\3ds Max 20xx\bin\*** for V-Ray for 3ds Max 2021 and earlier, or

***C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax20xx\bin***  for V-Ray for 3ds Max 2022 and later.


## **Accessing Parameters in CMD**

---


### plgparams

Details on plugin nodes from plugins is available with the plgparams.exe tool that comes with the V-Ray installation.

With the command prompt, navigate to the *bin *folder and run **plgparams.exe** without arguments to see a help message on the tool's usage. In general, you will need to run a series of commands to point **plgparams** to the plugin folder, locate the V-Ray name of the node (which might differ from its display name in the V-Ray UI), and list the parameters for the plugin.


To point **plgparams** to the folder where your plugins reside, use the -plugindir option:

```plaintext
plgparams -plugindir <plugin folder>
```

This command tells **plgparams** where to find your plugins. By default, the default plugins folder location is:

<span style="color: #333333">*C:\Program Files\Chaos\V-Ray\3ds Max 20xx\bin\plugins*</span>* *for V-Ray for 3ds Max 2021 and earlier, or

***C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax20xx\bin\plugins**** *for V-Ray for 3ds Max 2022 or later.


> ✅ The plugin folder must be specified with the **-plugindir** switch each time you run the command.


```powershell
## Example for 3ds Max 2021 and earlier
"C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plgparams.exe" -plugindir "C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plugins"
 
## Example for 3ds Max 2022 and later
"C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plgparams.exe" -plugindir "C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plugins"
```


To see the list of plugin names in this folder, use the following command:

```shell
## Usage
plgparams -plugindir <plugin folder> -list
 
## Example for 3ds Max 2021 and earlier
"C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plgparams.exe" -plugindir "C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plugins" -list
 
## Example foe 3ds Max 2022 and later
"C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plgparams.exe" -plugindir "C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plugins" -lilst
```


To see help on the parameters for a specific plugin, name the plugin in quotes after the **-plugindir** switch and folder. For example, to see help on the **BRDFGlass** plugin, use the command:

```shell
## Usage
plgparams -plugindir <plugin folder> <plugin name>
 
## Example for 3ds Max 2021 and earlier
"C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plgparams.exe" -plugindir "C:\Program Files\Chaos\V-Ray\3ds Max 2021\bin\plugins" BRDFGlass
 
## Example foe 3ds Max 2022 and later
"C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plgparams.exe" -plugindir "C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2022\bin\plugins" BRDFGlass
```


This will list all the parameters for the plugin and definitions for each.



### plugininfo

Navigate to the *bin *folder and run **plugininfo.exe** without arguments to see a help message on the tool's usage. In general, you will need to run a series of commands to point **plugininfo** to the plugin folder, locate the V-Ray name of the node (which might differ from its display name in the V-Ray UI), and list the parameters for the plugin.

To point **plugininfo** to the folder where your plugins reside, use the -plugindir option:

```plaintext
plugininfo -plugindir <plugin folder>
```

This command tells **plugininfo** where to find your plugins. By default, the default plugins folder location is:

<span style="color: #333333">*C:\Program Files\Chaos\V-Ray\3ds Max 20xx\bin\plugins*</span>* *for V-Ray for 3ds Max 2021 and earlier, or

***C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax20xx\bin\plugins**** *for V-Ray for 3ds Max 2022 or later.



```powershell
## Example for 3ds Max 2022 and later

"C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2024\bin\plugininfo.exe" -plugindir "C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax2024\bin\plugins"
```


To see the list of plugin names in this folder, use the following command:

```powershell
##Usage

plugininfo.exe -plugindir <plugin folder> -list

##Make the list organized by category

plugininfo.exe -plugindir <plugin folder> -list -listByCategory

```


To display the plugin information in a JSON format, use the following command:

```powershell
##Usage

plugininfo.exe -plugindir <plugin folder> -name BRDFGlass -json

##outputs the parameters of the BRDFGlass plugin in a JSON format
```

> ✅ The plugin folder must be specified with the **-plugindir** switch each time you run the command.
