Really awesome work! I have some questions: May I export the unity images in PNG format and use them in a commercial game? Is it allowed to alter the works (to use them in a commercial game)? Thanks in advance :-).
Ah, never mind, I was using an old project and tried to import the file which resulted in this error. I just created a new project and the import works fine, so no further issue here. Thanks for the fast support :-).
