@xaero96

Thanks a lot for your answer! What a shame ... and yes in that case it is strange I didn't notice it before. All is not lost though, as I took a screenshot from the original map, so anything within the square, I can recreate there.

So the tip here would be to either take screenshots or export the map (I didn't need the resolution, but the place markers) of singleplayer maps as soon as possible.

Is it possible to get the biome names when hovering over the full map?

No, sorry. I'm planning to work on that pretty soon but I'm doing something else atm.

I appreciate you responding and look forward to this maybe being implemented in a future release cheers!

Hope you can help me with my request.

It seems not to be a simple copy and paste task if you try to get your world map from a single player to a multiplayer server (all map data is on the client folder obviously). I also found no instruction which helps exactly with this. Unfortunately we had issues with open to LAN and going this way now which works way better anyway.

I tried copying the whole map folder and rename it to Multiplayer_MY.LOCAL.IP.123, tried copying the cache folders into the multiplayer folder mw$random_number identical to the server save folder but had no success. Also I found no real way to reload the map from the cache folders. Maybe I miss just a simple config adaption for it to work?

Any help is appreciated, thanks!

Hello,

im trying to figure out how it saves the map files since i want to convert my voxelmap files (around 200k files) to your map, as it seems much more optimized in terms of performance.

voxelmap now really struggles when scrolling around, especially when zooming out a lot.

after hours of trying, based off your post here:
https://www.minecraftforum.net/forums/mapping-and-modding-java-edition/minecraft-mods/2624027-xaeros-world-map-1-18-2-fabric-forge-1-17-1-1-16-5?page=36#c735

i cant figure out what im doing wrong.

im using processing3 for this, since im familiar with it. good for quick and dirty applications, but nothing serious.

my code that reads a unpacked region.xaero file (multiplayer) and tries to display it.

https://pastebin.com/CqK09wwT

(im on mc version 1.12.2, world map version 1.20.3.1, minimap version 22.2.0.1, forge 14.23.5.2859)

Correct me if im wrong but i understand it like this:

if the first byte is 0xFF, read another 4 bytes for version number.

if it isnt 0xFF, pass its value to step 1 in while loop.

while loop:

1. read 1 byte which is the section coordinate. if its -1 you reached EOF and break the loop.

2. loop trough chunks and check if the first pixel on each chunk exist

3. (for each chunk) if yes, go to pixel loop. if not, keep looping until all 4x4 chunks in this section have been checked, go to step 1 after that to get a new section.

Pixel loop:

loop trough the pixels (except pixel1, which takes its data from the "first pixel check" above. ),

1. each pixels reads 4 bytes (int).

2. if it isnt grass, read another 4 bytes. (state id) (1.12)

3. if its using the old height (format?) read 1 byte, dont if its the new height.

4. if it has overlays, read 1 byte which indicates how many overlays. loop trough them.

Overlay loop:

1. each overlay reads 4 bytes

2. another 4 bytes if its not water (1.12)

3. another 4 bytes when its colortype 2 & bit2 ist set

4. another 4 bytes for opacity if its not 1.

after the overlay loop:

1. read 4 bytes if its colortype 3 or one byte if its the second option.

im scratching my head since hours now, i really want to use that mod, but cant afford losing all of my map data.

Do you see the problem in my attempt?

Or does anyone ever tried the same and made a working converter?

id be grateful for any help im getting.

a small documentation about the current format would be very helpful.

the only clues i have so far is your old & new post and what Gjum on github provides ( https://github.com/Gjum/voxelmap-cache/blob/master/xaero-format.md )

i now ditched the idea of reading them and tried (based off the old version 1) to write a program that creates new regions (have to zip them myself for now, its just generating the xaero files)

https://pastebin.com/4buHYTGQ

it creates a region the map mod can read and display but before drawing the last chunk, it goes blank.

in the console theres this error multiple times:

[16:18:55] [Thread-15/INFO] [xaero.map.WorldMap]: (World Map) Retrying...

i seem to be missing a little bit of data? premature EOF.

i generated a sample file. https://filebin.net/azphqhxzhhd7ypx0/region.xaero

it just contains the 0xff and version header, the section coordinates and a int for each pixel.

I found a bug in the current 1.12.2 world map . Importing a fully formed rectangular map from Paper 1.12.2 , constrained with world border , into single player Forge 1.12.2 , world map will not read any of the chunks generated on the paper sever . Since the map was originally a single player map and moved to Paper , world map will only see chunks from when it was single player. Journey map , Dynmap renders the whole complete map , while world map will only render pre-Paper server chunks

I had already gone through your settings and had it turned on . Here is screenshots with debug on and moving the cursor over original old area and gradually in to areas generated while running in Paper 1.12.2 . Since your source is not published I cant guess whats wrong . the original map had a sea level of 64 blocks , In paper all the new area was generated at a height of 52 blocks using cleanroom generator plugin ,

environment: NORMAL
seed: '0'
generator: CleanroomGenerator:30,stone,20,dirt,1,grass

should not mater , Unless it is using height map of 64 of original map and does not see new chunks generated at height 52

One other observation in single player , I need to fly over the blank areas for worldmap to see and render my map . before suggesting i change any other setting , I had read through the help on what settings do and tried them out with no success .

I uploaded a part of the map here , so you can test . The first thing you do when opening the map is press M to render the map . Flying around will result in a full render . Leaving the generated area , will begin to generate new vanilla chunks . For this test , just stay in that area and see that it does not render the chunks generated in Paper . I think I see what the trouble may be . On a server the flatland artificially generated with cleanroom is set to The Void to prevent players from generating new chunks or seeing any land past the world border . Your mod must have a setting preventing reading void biomes , so player must fly over the area to render it . I guess we can use FAWE to change the maps biome to plains or something . I guess this is how your map renders the 2D map compaired to Dynmap or Journey map . Looking at the Level.dat may help you figure it out
