This is now possible by choosing the "Portable Prefab" (pfbx) file format when saving the prefab. The grouping info of all objects is preserved after importing, independently of the import setting "Create Group of imported objects". |

Thank you very much for filling both my feature requests w.r.t. preserving grouping. Will portable prefabs made in 2.7.1 be openable by earlier versions? (ofc without the grouping) |

No, the new files won't be recognised, it's a new format, only 2.7.1+ will be able to read that. |

The new option to export as a portable prefab (.pfbx) is a little too buried for my liking, as mappers may never think of trying to alter the "Save as type" setting. Also, a prefab is by definition "portable", so naive mappers might not realise why they should make a portable prefab instead of just a prefab. Is there maybe a way to make this backwards compatible, i.e. by extending the .pfb file with additional grouping information that gets ignored by earlier DR versions? |

Can't change the existing PFB format without breaking any older version out there, unfortunately. I agree that it might not get used at all the way it's listed now... I was tempted to make the PFBX format the new default in DR 2.8.0 onwards when exporting prefabs, but I wasn't sure if it was confusing for mappers. Do you see any downsides in making the portable format the default? |

The new .pfbx is better in every way than .pfb, so the .pfb export setting is only needed to make .pfb's that can be opened in older DR versions. Also, unlike map files, I don't think TDM cares if there's an x at the end of the prefab file format. That speaks for making this the new default. The downside is that not everyone's up to date with their DR version, but all that'll happen is they won't see those new prefabs, and with time they'll hopefully update. |

Ok, I'll see to making pfbx the default. TDM itself cannot load that new format, but it doesn't care anyway. The only place where prefabs are loaded is the editor itself. |
