I see rule 4 says "You may use pre-made asset packs, as long as you have permission from the creator" but I was wondering specifically if we can use assets we own. Humble Bundle had a bunch of awesome stuff this month - sound effects and music, 3d models etc. If you have a license to use something than obviously that is "permission from the creator" 馃槉 but I just want to make sure it is ok if we use assets such as these.
Thanks!
