Nice assets, but I find the licensing terms very confusing. LICENSE.txt says that I am allowed to modify and use this asset pack commercially. However, your CREDITS.txt lists a third-party (CombatExtended) as a source which says that modifying and commercial use are prohibited.
So unless you specify which assets originate from that CombatExtended, any responsible user must treat all of the assets in this asset pack as Creative Commons 4.0 NonCommercial (NC) and ShareAlike (SA) since that's how the original creators licensed them.
Would you please clarify the situation?
