I know what you said, I was just quoting the rules. However I went back a reread the entire rules and does this look like a contradiction to anyone else?
“Submission may
include sourced (non-original) assets, provided that (i) all sourced (non-original) assets must be
noted, and (ii) unless such sourced (non-original) assets are from the Unreal Engine Marketplace
(“Marketplace Sourced Assets”), such assets will not be reviewed or scored.
Submission must not include assets created prior to the Contest Period (outside of noted sourced
assets).”
and
“Sourced (non-original) assets will not be reviewed and scored.”
This quotation is from the judging section of the rules, not sure if that makes any difference.
