Failed to render Nether/End with NullPointerException about blockmap HOT 10 OPEN

I walked around in the Nether and rerendered, and it doesn't seem to show any unfinished chunks in the area where I walked, so I'll consider that to be a good sign! (Unfinished chunk pins are off, but the corrupt chunk pins are on.)

after:

I am sorry, but the download link requires me to log in. I suspect that it is bound to your files from your account, so it wouldn't work either way. If you don't mind, please send me the failing file (r.-2.-3.mca in the End folder).

GitHub won't allow uploading .mca files, so here it is in zip format: r.-2.-3.zip

I just pushed a potential fix to the develop branch, please check it out

from blockmap.

Thanks, I built the CLI jar from the develop branch and confirmed that my original CLI commands run to completion and no longer produce any errors, so this seems like an improvement.

However, by building manually, I was able to run the GUI for the first time ever (since I am on Windows), and based on the pins, it still seems to note a bunch of corrupt chunks in the End and in the Nether dimensions only. It seems potentially related to the original issue.

End example here:

java.lang.NullPointerException: Cannot read field "isTranslucent" because "colorData" is null

Nether example here:

java.lang.NullPointerException

This makes me think something still isn't quite right...

For comparison, here is a rendering of the Overworld:

from blockmap.

In the released GUI, there are lots of "Corrupt chunks" in the Nether dimension:

In the develop branch GUI, those are instead shown as "Unfinished chunks" in the Nether dimension:

In the released GUI, the End has many "Corrupt chunks" as well:

In the develop branch GUI, the End only has a few "Unfinished chunks" and doesn't show any "Corrupt chunks." It also only seems to display the "End city" pins that are near an unfinished chunk pin, and the rest do not appear for some reason.

from blockmap.

Thank you for the information. My fix does not appear to work as hoped. I have pushed a second attempt onto the developer branch, please try it out and see if it improves things.

from blockmap.

I downloaded the new version and ran gradle regenerate and gradle previewRelease, like I did last time. Here are the results from the GUI:

I am not sure what changes I am supposed to be looking for, but I don't see any obvious difference from since previous commit. I still see the same number of "Unfinished chunks" pins as before.

from blockmap.

Try walking to those "unfinished" chunks in Minecraft. If they render fine afterwards, nothing's wrong. Otherwise, please send me a region file with them so that I may take a look.
