whooww, I'm amazed that I found software like this, searching for map renderer for large maps for about 4 hours and couldn't find one that could do this, as from the description and comments I'm almost sure it does its job, but I couldn't make it work, windows 10 user trying to render 1.12.2 minecraft world map, It doesn't output any image on default settings, with "map" output it just throws bunch of region named png images that are all transparent, i'm running program as an administrator, please help me get this excellent map renderer results.
p.s I'm going to test this on my neighbours pc ASAP, to make sure it does work
tried it out on windows 7 64bit, unfortunately no success, tried on large and small maps, not getting any results, do I have to install any library to make this program work? ( I have almost all the visual c++ redistributables installed)
I am sorry that it did not work out for you. I have gotten reports on this, and stumbled upon it myself but lost the result. Could you upload one or more of the files here so I could try it out? Would love to help you out to fix this problem.
The difference between "Map" and "Image" is that "Image" will create one single image of the map, while "Map" will create one image per region. I do have support for "one file for each chunk" and also more rendering options, but I have limited to this option only due to both performance reasons, but also those are only for easier debugging.
For everyone that stumble upon this issue, please upload a sample of the map so I can debug it.
An update to the development, is that I did not notice that the save format for MC 1.16 have changed slightly, so I need to adjust the parser so it can support that.
Edit: Found the fix and also sample data for black regions. In this case, it works if I draw an image, but does not if I draw a map. I am investigating and meanwhile trying to improve performance.
Edit2: The black regions are actually just regions that have been created with chunks, but no blocks have been generated. The fix for this would be to ignore them entirely. This makes it quite complicated to know what to keep and what to throw away until it has been fully processed. I may have to redesign parts of the system to make it easier to adjust toward these kind of issues.
tl;dr: A fix for the new save format has been added. The "black image output" bug has not been found.
