Art sources: maps from a server that runs nothing
A map a server has never sent you has no colours on your client, and there is no packet to ask for them. That is the whole reason a shop or auction page draws blank parchment. Those colours are, however, sitting in the server's own world folder, and an owner who publishes that folder gives every player somewhere to read them from.
No plugin, no restart, no open port. The new map-export tool reads a world folder or a backup zip and writes out every filled map in it. Copy the result to any static host, and players point Art source at it in the settings. It is on the GitHub release, and read access to a world backup is all it needs.
Off by default and set per server, since a map id means a different picture on each. Three shapes are read: the mod's own cache files, a bare colour array, and a 128x128 PNG.
Nothing fetched is believed. Colours off a web host are a stranger's word for what a map looks like, so they are stored marked as a guess and Strict previews refuses them outright. If the server later sends that map for real the two are compared, and a source that gets three locked maps wrong is switched off and everything it sent is thrown away. Only https unless the address is your own machine, redirects are refused rather than followed, and an address pointing into your own network is turned down.
Fixed: maps went blank after a portal
Walk through a portal just after opening a shop page and the art came back blank and stayed blank, leaving only maps cached from an earlier visit. Two halves of one bug, and each on its own was enough:
- The client throws away every map it knows when its level is rebuilt, which a dimension change and a death both are. The Paper plugin kept a record of what it had already sent so as not to resend 16 KB every pass, and that record only cleared when the player quit, so for a whole resend window it deliberately sent nothing to a client that now had nothing.
- The cache had the matching hole. Received maps were written in batches off a timer, and a batch held only the ids: by the time it ran, the level it would have read the colours from was gone, so a map that arrived in the seconds before the switch never reached disk either.
Both are fixed. Update the plugin as well — the server side of this is in 1.1.1+paper.
Fixed: maps the plugin was not looking for
Item frames, glow frames, armour stands and display entities are how a shop front is usually built, and none of them were read. A merchant's trade offers are not in its inventory at all, so a villager selling map art showed nothing however long you stared at it. Nested containers now recurse, since a bundle of maps inside a shulker box used to stop at the box. A new debug toggle names every map sent, and every stack naming a map the server cannot resolve, which separates "not looking there" from "another plugin drew that map straight to packets".

Why beta
Art sources are new networking code, and the exporter has not yet been run against a production world outside its own tests. Everything else is covered by the usual suite, plus a client gametest that fetches over real HTTP on loopback and checks that a source handing over the wrong bytes is refused.
