Choppy Animation

#1
Today I tried to export my first animated windgenerator to FSX. In 3D Studio the animation is smooth and looks fine, after exporting to MDL (P3D SDK) the animation is choppy, the position of the blades changes every 5 seconds to random rotating positions.
Are there some special settings in 3DS configuration, i.e. framerate?

FSX requires at minimum five keyframes: 0 - 25 - 50 - 75 - 100, every 25 frames equal to 90º rotation.

Also make sure your animation controllers are set to Linear. The default in 3ds max is Euler which gives unpredictable results in FS.

Bill,
it was the keyframes, blades rotating smooth now in FSX. Also set framerate to 20, FSX internal framerate is about 18.2 if I remember correctly.

That was the hardest lesson to learn. Unlike FS9, FSX requires more keys to be set.

2 keys at 0 - 100; no movement at all
3 keys at 0 - 50 - 100; flips and flops erratically
5 keys... ; obviously works
