well I know my mur'loc model was based off the slave, made very hd, has animation titles stand, stand alternate, stand upgrade first, upgrade second, third, fourth, fifth, sixth, seventh, and eighth, no such grapple hooking or climbing animations how ever. not ever animation works either.
Is that sounding more like what you're after? its incomplete but I could let you have it any way, to start your custom unit data stuff, if you're willing to wait for it to be completed. Im not sure when im going to complete it, so if you do want it, it can be given to you as a WIP (work in progress)
