Can anyone tell me if the `cdb-to-3dtiles` converter utility found at [GitHub - CesiumGS/cdb-to-3dtiles: Convert CDB to 3D Tiles · GitHub](https://github.com/CesiumGS/cdb-to-3dtiles) is still in active development? From the looks of it, it appears it’s gone cold. There are four outstanding PRs that haven’t been addressed since 2024…
Thanks for any help in advance.

The last code-related commit was ~5 years ago. So even though I haven’t formally confirmed this, I’d say that it’s no longer maintained. Is the reason for asking that there’s a missing feature, an issue, or did you intend to open a PR…?

Thanks for the feedback.
In answer to your question, probably both missing features and the outstanding PRs. I’ve already addressed one of those PRs locally but I’m surprised no one has allowed the others to get merged into the trunk as they seem important.
If there’s no active development taking place for this tool, I may forge ahead and try to implement some of the features I need for my project. If there is no one available to approve the current PRs or future PRs, not sure what to do about that other than keep future development local…
Thanks

The last (larger) activity in that repo that I’m aware of was [This PR adds support for 3D Tiles Next by sanjeetsuhag · Pull Request #58 · CesiumGS/cdb-to-3dtiles · GitHub](https://github.com/CesiumGS/cdb-to-3dtiles/pull/58) , which was supposed to update the library to generate 3D Tiles 1.1 instead of 3D Tiles 1.0. I don’t know the latest state of that, but the development stopped and it was never merged. So any pull requests that could go into the main branch _now_ would have to be aligned with this branch, **iff** it was ever supposed to be merged.
I’d be tempted to at least check things locally so that I’d be able to test and approve smaller PRs, but … I’m currently on Windows, and [Support window build by baothientran · Pull Request #35 · CesiumGS/cdb-to-3dtiles · GitHub](https://github.com/CesiumGS/cdb-to-3dtiles/pull/35) has never been wrapped up, and dozens of conflicts in the meantime. So… the whole project seems to be stuck between a rock and a hard place, and unfortunately, I cannot say more than “it is what it is” right now 😔

Yes, it looks like a mess for sure. I noticed that RMTexture and RMDescriptor were mentioned in the PR #58 above. That is functionality I need.
I also noticed that with the current “trunk” code that I cloned, there’s no support for .gpkg files even though OGC CDB 1.2 allows for them as an “option”. I was going to at least add that.
Not sure where to go from here. I may try to start with trying to merge the main branch with PR #58 and see where that goes. I’m also on Windows, but I’m building and running the converter in WSL.That has gone smoothly and I got it working to convert Elevation so far.
I appreciate your help and feedback!
