Exception: cannot create im

[Tortoisecraft]

Hello, and thank you for contributing this tool to the PZ community!

Issue: I've tried to render the map twice and gotten the same failure towards the end of the process each time, copied below. Any help troubleshooting is very much appreciated! Can provide more info upon request.

Steps taken:

1. Downloaded and installed Python, checked box to add to PATH
2. Downloaded and extracted pzmap2dzi zip
3. Ran install_requirements.bat
4. Configured conf.yaml to reflect my pz_root and desired output_path
5. Ran run.bat
6. Encountered similar error as pasted below
7. Ran run.bat a second time
8. Encountered the error pasted below

All done

Finally, here are the two lines of conf.yaml that I touched (I did not change the mod_root to reflect my actual workshop path since the readme specifies "if you want to render a mod map" and I do not have any mod maps -- could this have caused the issue?):

pz_root: |- # project zomboid game folder
    C:\Games\Steam\steamapps\common\ProjectZomboid

output_path: |- # render output folder
    D:\Zomboid Map

You can try to turn off shared memory acceleration by setting enable_cache to false in conf.yaml, and see if that can help.

That resolved it! Thank you very much for the help and the tool. :)
