|  | **Cloud Batch Render** – Renders multiple views in Chaos Cloud. |
|  | **Export V-Ray Scene** – Exports the V-Ray Scene file to be rendered in V-Ray standalone. |
|  | **Chaos Collaboration** – Opens the [Chaos Collaboration](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/161317300) panel, where you can upload your renders and gather feedback from your co-workers and stakeholders. |
|  | **Pin **– Prevents the dropdown render menu from collapsing. |
| **Quality** |  | **Quality **– Provides a dropdown menu with a specific set of presets. The preset settings range from very low quality “Low” to “High+”. *See the **[Quality Preset table](#QualityPresets)** below.* |

|  | **Dome Light **– Uses [V-Ray Dome Light](https://docs-chaos.atlassian.net/wiki/spaces/VREVIT/pages/160989293) as environment lighting. Creates an imaginary dome above the entire Revit model. The dome emits light based on the mapping source that is
used, either a color or an HDRI image. |
