Jeez, it would have taken you like 10 seconds to send a PM asking for permission. As it says in the readme, the textures in my mod were the work of Levi Davis/nineball who gave me permission to use them. Unauthorised distribution by other people is not cool.
It would be very easy to make your own mod that makes use of either the textures from my mod or Prime's without actually distributing that content. Especially when the requester already linked to both mods so either already has them or can obtain them.
