I've been banging my head against the proverbial wall trying to get this to work, to no avail.

Basically, all I'm trying to do is hide/reveal a mesh during my animation using scale keys. I have it keyed at a scale of 1 on one frame, then 0.001 on the next frame. The animation is baked to the geometry itself, so there are no additional pivots at play, just the mesh's pivot.... yet I keep getting the following error:
// Error: line 1: Transform 'musician_gamePad' has different scaling and rotation pivots, this is not supported, ignoring scaling pivot! //

I tried setting the keys to Stepped and using the -dsa 2 flag but nothing works.

After exporting, the mesh in question is invisible initially, then becomes visible in the correct clip--working as intended, so far... however, once I play the clip where the mesh is visible, it STAYS visible in all the other clips permanently when it should become invisible when playing another clip.

Am I missing something? Why doesn't scaling work?
