Blockcrafter-export fails with an error with Python

[Shadowdane]

[edit] Cleaned this up as it was kind of a mess!

I got the 12 pixel texture size working in Mapcrafter with Minecraft 1.16.2, but the Mapcrafter output is way too big (~13GB) at so needed a smaller texture size which brought me to Blockcrafter from the other Issue I had posted in mapcrafter/mapcrafter#374.

I got Python working and installed the Blockcrafter package, but attempting the blockcrafter-export command fails with an error below.

@elamperti I gave up on the Docker option, I'll edit this post to remove that. Working on trying to get Blockcrafter working on Python, as got a lot farther with that and actually get a crash/error. Is there any additional details needed to diagnose the problem?

Here is the version, installed packages and the error I'm getting.

I noticed in a different thread that Python 3.7 is supposed to be used for blockcrafter. I just uninstalled Python 3.8 and installed Python 3.7.

The script seems gets a bit farther using Python 3.7, at least a window (VisPy canvas) opens but still crashes with the following error below. The window stays up and I left it up for about 6hrs but nothing ever happens with it. Previously on Python 3.8 a window would open/close instantly couldn't ever see what was popping up. So at least it's a different result! According to what I can see in the error seems to be crashing on a different lines compared to before.

I hope this helps!

So what versions does blockcrafter work on??

I tried running it on the 1.15.2.jar file but it fails on that too but seems to get farther in the process of doing a valid export. It does write one file .\blocks\isometric_0_8.txt which has 1475 lines in it, but fails with the error listed below.
