Compliance
No texture file may violate any Hive Workshop general or specific site rules.
75% Modification
A skin must be modified at least 75% from the original in order to to be approved.
Original Work
Textures not created by the submitter are prohibited. If users make a skin inspired by a particular texture, full credit must be given to the original author.
Shading
Shading must be appropriate on the skin and look correct in-game.
Copy and Paste
No CnP from existing custom skins is permitted. A maximum of 25% CnP from default Blizzard textures may be acceptable, providing that the skin is well executed.
Recolors
Recolored skins may be accepted, but only if the rest of the skin follows the above rules.
Copy & Paste
CnP & recoloring cannot be used on the same texture (for instance, having 25% CnP & 25% recolor (50% total) wouldn't be allowed, but the total of 25% would be).
Approval
Resource moderators will decide on a case-by-case basis which skins are original or useful enough to be approved. If rejected, the moderator must detail why the submission is unacceptable.
