This page provides information on V-Ray Attributes that can be added to 2d Placement and 3d placement nodes.

<span style="color: #000000">The V-Ray Additional Attributes can be added to 2d Placement and 3d placement nodes. This is done from the </span><span style="color: #000000">**Attributes > VRay menu**</span><span style="color: #000000"> in the Attribute Editor with the placement node selected.</span>

<span style="color: #000000">In cases where geometry objects have multiple UV sets, this allows for explicitly specifying the uv set to be used without the need for going through the UV Linking menu in Maya, and thus avoiding any connections between nodes by simply inputting the name of the UV set.</span>

<span style="color: #000000">In cases where the geometry is a </span><span style="color: #000000">[VRayProxy File Formats](https://docs-chaos.atlassian.net/wiki/spaces/VMAYA/pages/111744312)</span><span style="color: #000000"> reading a .vrmesh or .abc (Alembic) file(s), the UV set field can be used to specify custom attributes coming in with the proxy. One of the most common use-cases is to read </span><span style="color: #000000">***Rest Position***</span><span style="color: #000000"> attributes from Alembic files coming in from Houdini to make 3D textures follow the object deformation.</span>

The same attribute can be added to Maya's SamplerInfo node to help specify the UV set to be used when using the samplerInfo's U and V output connections.

## **Notes**

---

- The UV set name field is **case-sensitive**. V-Ray will not be able to use the correct UV set if its name is mistyped, in which case the currently linked UV set, as specified in the UV Linker, will be used.
