Currently the Minecraft Wiki uses Mineshot to render structures. But it is very hard to position yourself in the right place, and make sure the lighting is correct, and chunk culling causes problems with larger structures. It would be nice if we could render structures with this mod too.

this one could be a bit difficult, but, sure, I'll try

Orbis somehow renders structures as items, possibly could piggy back on item rendering, just like how I described in #12?

Orbis is closed source, so, I can't inspect the code, and would rather not depend on it.

https://git.gildedgames.com/GildedGames/OrbisAPI Is it not here?

Either way, I don't see a license here, so this is visible source at best.
