Description
**Describe the bug**
If you make a geometry light in instances, the light still lights the scene but in incorrect position .
**To Reproduce**
Steps to reproduce the behavior:
1. Make a mesh a geometry light.
2. Set instance or not.
3. Render with Solaris viewport.
4. Here's a repro Houdini scene:[meshLight_instance.zip](https://github.com/Autodesk/arnold-usd/files/10683074/meshLight_instance.zip)
**Screenshots**
The only difference between the 2 scenes is that there is instanceable or not .


**Used Software Versions**
- HtoA 6.1.4.0
Contributor guide
Research direction
Open meshLight_instance.zip in HtoA 6.1.4.0 and reproduce the comparison in the Solaris viewport with the mesh light instanced and non-instanced. Done means the instanced geometry light illuminates the scene from the correct position, matching the non-instanced result.
