Both are very good, but require some work to finish.
Revan Flowing Robes: possibly the one that requires most work. Unlike the magnificent Revan Revisioned mod, which is completely clip free, this one still features major clipping with 1h and 2h weapons, both ranged and melee (cape goes inside the body when strafing or dodging, for example, and the run animation is very innatural).
Nihilus animation fix: this one is mostly finished, but features some weird clipping. Walking with a lightsaber, for example, causes major clipping between feet and cape, while having a 2h ranged weapon doesn't. Curiosly, pressing the X button features a clip free animation. Oh, and strangely enough, then pressing "X", only the lightsaber makes noise - other weapons, whether melee or ranged, are mute. Could it be due to Nihilu's unique spinning animation?
