UHC PvP Texture Pack "Azure UHC" was made by Celestial & Crayola (YouTube). They also submitted some of their custom PvP Packs to be reviewed by Pack Nation. Some of their other creations are: Red & Blue UHC, Deep Sea and Navy Blue Pack. According to the creators the UHC Resource Pack was made for for Version 1.7/1.8. We didn't try to use it with 1.9.4/1.9, 1.10/1.11 but it might be compatible with 1.9/1.10/1.11!
