LoopEnd

Flag:	LoopEnd
File(s):	Art(md).ini
Values:	Unsigned integers
Default:	last frame of the animation
Applicable to:	Animations

Specifies the 1-based ending frame for this animation when the total number of iterations is more than one. See Animation Looping for more info.

It should be noted that while as a rule it is an exclusive end frame, this isn't always the case, there are exceptions where the LoopEnd has to be 1 less than the expected value. One example being the Iron Curtain animations that use NAIRON_F as the artwork. Why this happens is unclear, but it might be related to the .shp compression used, relegating it to some legacy/alternative code path.
