No.. "Texture Coordinate Editor" built into MilkShape
And no, it wasn't a pain at all to animate the spiral door. First, I set the max frames to 55. Then I just placed a join at each rotation point of each section, independant from one another. Unchecked "Animation->Operate on Selected Joints Only" and hit Ctrl+K to place a keyframe at frame 1. Then I moved the slider up 15 frames, rotated each joint clockwize 90º and hit Ctrl+K. Moved it to 40 without touching any joints and placed another keyframe for the pause, and finaly, at frame 55 I rotated them counter-clockwize 90º and hit Ctrl+K. Then I can play the animation
And I fixed the indent in the first door
and accidentally added rust here
