Hello. I downloaded my asset pack to check if this was true and you're right! It only does contain the .blend files. I'm sure that when I bundled everything together there were also .fbx and .obj files.
Sorry about the trouble. I'm adding the contents in right away, and thank you for the comment.
Hello doomtucan. I've corrected the file upload, so now the .fbx and .obj files are present. Thank you again for bringing the problem to me as I was able to fix it for other people in the future. :)
