* Previously rejected any `face_limit` — now validates and passes it through.
* PBR remains unsupported (hard error).

<figure><img src="/files/HbgboAaOnVihCuXz1udG" alt="" width="563"><figcaption></figcaption></figure>

* Trellis 2 also updated: minimum decimation target lowered from 100k to 20k, added PBR hard error (was silently ignored), added texture-off override warning.

* **Tripo3D v3.1** added

* **Meshy** — additional generation arguments added

<figure><img src="/files/KtzxtZn4uBPxNbXY5y6b" alt="" width="501"><figcaption></figcaption></figure>

<figure><img src="/files/yEI9VckdxiSWiyW3PFNs" alt="" width="563"><figcaption></figcaption></figure>

* **Migration** (v0.9.49) — Existing projects with 404-GEN or Trellis 2 backends and `pbr=True` are auto-migrated to `pbr=False` to prevent execution errors.

**Audio format switch to MP3** (#987) — Comprehensive refactor of the internal audio format from WAV to MP3 320 kbps:

* **All audio nodes** now output `.mp3` / `audio/mpeg` instead of `.wav` / `audio/wav`.
* Uploaded audio is now converted to MP3 (320 kbps) instead of WAV.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.atlas.design/atlas-ai-studio-overview/release-notes/release-0.17.0.md?ask=<question>&goal=<endgoal>
```

`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.
