# 2021.2.0 - January 14, 2021
Environments
`Preview`, `Admin-FTS`
###
### Augmented Reality
**Generate AR** at scale to create the fastest experiences and review AR assets. We’ve expanded the Render workflow to include AR as an output type. Select AR and whether you want to generate `glb` (Android) or `USDZ` (Apple).
**Rapid Compact asset optimization** library has been added to crunch `glb` and `usdz` assets for the best file size. Using ‘Rapid Compact Commands’ you can set specific optimization settings. You can save and reuse these settings using the `Preset` feature.
*Please note that this is a pay-per-use service, speak to our Customer Success team to learn more*
### Assets
**Add Asset** screen has been updated to group asset types and provide sub-types via dropdowns:
**Material Proxy Operator** provides the ability to create a “universal material” that can be used across experiences: you can specify a separate material for WebGL 3D, Virtual Photography using VRay, and for Augmented Reality to generate the best experiences. This also means that you can use one Catalog record to reference a single Proxy Material.
Convert any existing materials to a Proxy Material using the “Convert” button in the Properties Panel:
Your original Material is retained and you are provided slots for alternative Materials by output type:
You can also use logic to set these values:
### Performance
**Performance Best Practices** has been published and is available [here](/learn/workflows/best-practices/performance-considerations.md). The best practices help with optimization assets, using caching, and the player loading improvements we’ve implemented.
### Bugs / Cases
GL6254 - Asset autosave doesn’t work with custom scripts\
GL6350 - Clara importer doesn’t work with async scengraph refactor

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://community.threekit.com/releases/2021/2021.2.0-january-14-2021.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
