Error exporting models built with Sprytile #36

I'm not sure why:

Blender quit
Build took 0.6751s

The error leads me to believe it has something to do with the way this plug-in sets up UVs?

ZedCode commented 6 years ago

This is interesting...I updated my operators.py file starting at line 93 to look like this:

try:
    json.dump(data, f)
except:
    print(data)

Now when I try to run the conversion I see:

I'm guessing the base64 encoded junk is the issue?

ZedCode commented 6 years ago

Ah, wait, it's:

'sprytile_mats': [<bpy id prop: owner="SCScene", name="", address=0x7fb063282628>]

Is not valid JSON.

Moguri commented 6 years ago

Can you please supply a blend file demonstrating this issue? Thanks!

ZedCode commented 6 years ago

You should be able to checkout this repo: https://github.com/ZedCode/problematicBlend turn it into a BlenderPanda project and observe that it creates the intermediary file but not the final .bam file.

Moguri commented 6 years ago

The model is now exporting for me without errors with 75dd34cbf00ed3a40851ffa412457d1763af8da2. It also looks correct in pview. Do you have any other files showing issues with Sprytile?

Moguri commented 6 years ago

Closing this due to inactivity. @ZedCode, if you're still having issues, feel free to re-open this issue or create a new one.
