RCP 3 adds a lot of artist-facing surface: lightmaps, Animation Graph, Script Graph. Are step-by-step, artist-oriented tutorials planned beyond the API reference docs? A guided onboarding path would help 3D artists adopt these features much faster.
I'd recommend taking a look at the following WWDC26 sessions, if you haven't had a chance to already:
- Iterate your spatial scenes faster with Reality Composer Pro 3
- Design no-code games with Reality Composer Pro 3
- Supercharge your spatial workflows with Reality Composer Pro 3
- Extend Reality Composer Pro 3 functionality with Xcode
These sessions provide an approachable introduction to all the topics you've mentioned, including Animation Graph, Script Graph, Compute Graph, and baking lightmaps.
In addition to these sessions, the Reality Composer Pro page is a valuable resource for tutorials and documentation as well.
If you still feel there are gaps remaining in the documentation, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.
If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?
Thanks!
