Live-Syncing Unions

[Kampfkarren]

I don't know if this is an rbx-dom issue or a Rojo issue, but either way there's no way for unions to sync right now. Blocked externally (no way for plugins to recreate unions right now?).

Would love to do this eventually!

Is this actually blocked? There's APIs on the plugin object for this: https://developer.roblox.com/api-reference/function/Plugin/Union

Importing rbxm/rbxmx unions is, but I guess unioning un-unioned Parts/NegativeParts is not. @tiffany352

There is an API for creating unions with the plugin, see BasePart:UnionAsync and BasePart:SubtractAsync.

The problem is more about dealing with the data as it's stored on-disk and figuring out how to turn that into instances in real time. While we'll be able to use files built to disk to load unions, I'm skeptical that it's even possible to try to interpret that data, create parts in a plugin, and join them to match the original geometry.

For completeness, we know that we can solve this at least in one direction with #205.

I believe the only solution for this is going to be #205. We can open a new issue in the future if there are specific issues for unions, but until then, I think we should lump them in with similar instances.
