World conversion of versions < 1.13 issues

[Macintosh-Fan]

It's great that < 1.13 worlds are now supported. But, since it's new, there are going to be some problems, so this is just one of them to note.

It seems like different blocks of the same type of wood are considered the same.

I'll update the issue if I discover other texture problems.

Yea, there are quite a few holes in the loading of older maps and I'm not too sure if it's something that's worth fixing. You're always gonna get a better result by upgrading the world to a newer minecraft version.
I have a couple of ideas of how it could be fixed but it's messy. Biggest stuff is doors are just missing, fences and glass panes as you see don't have the connections and corner stairs don't work.

Do you know of any program that could convert 1.12.2 to 1.19.3 or something like that?

I don't, I would just recommend doing it in minecraft, do a quick fly around the areas you want to export to make sure they're fully loaded and converted.

I think portals are also a bit messed up

Instead of flying around the world, in the "Edit World" screen in Minecraft, you could press "Optimize world" button and it should upgrade the chunk format for the whole world.
