Hi everyone im having a problem with my model in addon builder. It fails to build due to the model not being loadable. A screenshot will be included so it will be in more detail. Any help would be great thanks.

the model might already be binarized and that's why it's throwing an error.

No the model  isnt already binarized. Would there be any other reasons ?
