### Example: Instancing vrscene with MASH and nParticles
MASH example
This example shows how to instance a vrscene using MASH. A .vrscene is imported with the Scene Manager. The vrscene used in this example consists of one geometry object (an owl), which has a material applied.
In the VRayScene rollout, change the Load Mode to Geometry. This way, the scene will load only geometry and shading, but it will become available for instancing.
To instance the scene using MASH, create a MASH Network (MASH > Create MASH Network ). As a **Geometry Type**, select **Instancer**.
Adjust the distribution of your MASH network. In the example shown, the original owl scene is instanced 9 times. The instances are distributed in a Grid, with **Distance X** and **Z** set to **50.0**.
The new scene is ready to be rendered or exported as a .vrscene, allowing you multiple instancing of one vrscene.
nParticles example
Here is how to instance a vrscene with nParticles. Import the .vrscene using the [Scene Manager.](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111742808) The vrscene used in this example consists of one geometry object (an owl), which has a material applied.
In the VRayScene rollout, change the **Load Mode** to **Geometry**. This way, the scene will load only geometry and shading, but it will become available for instancing.
Create the nParticles using the **nParticle tool** (nParticles > nParticle tool). Select the points in the viewport that will later be instances of the vrscene. Press **Enter** to create the nParticle node.
Go to nParticles > Instancer. Select the newly created **instancer** node and add the vrscene as an instanced object:
Once done, the vrscene instances load in the viewport and are ready to render. In the example below, the points of the instances are randomly selected.
Note that if you miss to select the **Geometry Load Mode** of the vrscene, the render will not include the instanced geometry, although it will be visible in the viewport!

### **Snippet Example**
**Example: Material Override**
```
// MATERIAL OVERRIDE EXAMPLES // // Create new shadeless material. BRDFLight shadelessBrdf { color=Color(0.15,0.35,0.35); affect_gi=false; } MtlSingleBRDF shadelessMtl { brdf=shadelessBrdf; } MtlWrapper shadelessMtlAlpha { base_material=shadelessMtl; alpha_contribution=-1; }
```
**Example: User Attributes Override**
```
// USER ATTRIBUTE OVERRIDE EXAMPLES // // Override user attributes that are used to replace a string in texture paths Node pSphereShape1@node { user_attributes="texPath=/tmp/assets/"; } // Override user attributes that are used to pass a color Node pSphereShape1@node { user_attributes="color=1,0,0"; }
```
## **Notes**
---
- *.vrscene* files can be exported when you turn on the **Export to a .vrscene file** option in the [Common tab](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111739309) before rendering the scene or via Maya's FIle menu > Export All.../Export Selection option.
- Cameras and render settings are not imported from *.vrscene* files even if they are present in the files themselves.
- VRayScene supports loading sequences of vrscenes where each frame of the animation data is stored in a separate file.
- Light linking of a .*vrscene* asset and a light affects all instances of the .*vrscene*.
- When VRayObjectProperties is used on a VRayScene node, the **Override motion blur samples** option has no effect, as it is baked to the VRayScene and cannot be changed.
- V-Ray supports* .vrscenes* containing files with long names on Windows when the corresponding option is enabled in the system settings. Refer to the official [Windows documentation](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry) for instructions on how to enable long file name support.
