While trying to import any Cyan prp.

D'oh! I wish I knew what was causing the extra issue with anim class import, but it should be fixed now. Download Latest.zip again and let me know if it works.

That is strange. Since alc_AnimClasses is imported with...

Code: Select all
from alc_AnimClasses import *


...it does not need to be prefixed with the name of the module.

Is alc_AnimClasses.py in your scripts folder?

yes, I've had the same problem multiple times when testing the export. The file is clearly there, and I have no idea why it's causing the random errors :(

Is this a situation where two modules are trying to "import" each other? That's usually what's going on when I see mysterious import problems.

Yes, alc_MatClasses and alc_AnimClasses are importing each other.

And alc_MatClasses is importing alc_AnimClasses in two different ways. I guess this needs some code cleaning.

Yeah, you really want to import the minimum necessary in any given file.

It also helps a lot to move import statements to the *end* of the file, where possible. It's not always possible; if you're declaring some "class X(Y):" then Y has to be imported up top. But if you only use a symbol inside a function (or method), then its import statement can be at the bottom of the file. And that avoids a lot of the trouble.

(Mutual imports aren't illegal; you just have to be careful.)
