How to export animation for display in sketchfab?

Well its easy… only you have to use bones (joints) and export fbx. But… there are situations where one wants to use other ways of animation..
Say you want to do wind for flag, or noise modifier for plants. or just use bend modifier (deform, nonlinear, bend). Yes, you could do same transformation with bones/ joints… but that’s like 10 times more work.
So you might know that fbx / sketchfab also supports morph targets (blend shapes).
So here is what you do – just copy paste your object with animated modifier as many times as you you need. (you will have to experiment with numbers of copies needed)
Now you go through timeline and convert animated object to static mesh. And use these as morph targets (blend shapes).
Wuala!.
