I have been working on this for a couple of days, baically I got most of the mods from FTB Unleashed and compiled them to the one. Please note there is still some bugs and stuff like that in this texture pack.
We had some known bugs which we believe are fixed but we are having weird issues with tanks, I had fixed it and loading great on my own computer, but when another player downloaded it and used it it seemed to be bugging a lot. It seems to be working fine now though but if you find this bug please let me know by commenting on this post.
ALSO NOTE: I DID NOT MAKE FAITHFUL 32x32, I COMPILED IT FOR FTB UNLEASHED. YOU CAN FIND THE ORIGINAL THREAD HERE.
Please note that this is 32x32 and may have some issues if Optifine is not installed. You can probably use MCPatcher but I have never tested this with a FTB pack.
