The Contest is open to participants 16 or older.
“Submission may include sourced (non-original) assets, but the sourced assets must be noted. Submission must not include assets created prior to the Contest Period (outside of noted sourced assets)”
“Sourced (non-original) assets that aren’t from the Unreal Engine Marketplace will not be reviewed and scored.”
Yes, you can use any content made prior to the jam (as long as it’s noted in your submission) but we don’t judge that content and we don’t score it. This has been the case previously. The special rule for this jam is that we DO judge and reward score for Marketplace assets.
Let me know if that clears it up!
