Yeah, you can’t do sub-frame-key-repeats in messiah, but when I need that, I normally set up an expression. What kind of keyframing do you need? Maybe I can help out?
Fine displacement with some fast animated AoN shaders should at least give you something similar?
If you repeat the same displacement-animation per frame, you should even be able to get rid of the flickering, or most of it…
Cheers!
