Description
On the attached [light_block_bug.zip](https://github.com/Autodesk/arnold-usd/files/10220519/light_block_bug.zip) usd scene, when we change the value of the attribute `density` of the prim `/world/lgt/blockers/AAA/BLOCKER/blk_001`, the render delegate doesn't update where it should.
**Used Software Versions**
- Arnold: 7.1.4
- USD: 22.08
Contributor guide
Research direction
Start with the attached light_block_bug.zip USD scene and reproduce changing density on /world/lgt/blockers/AAA/BLOCKER/blk_001 using Arnold 7.1.4 and USD 22.08. Trace how the render delegate handles that prim's attribute change; done means the render updates after density changes.
