...course! Meshinstance always have been like a godsend for who be looking for some
unlineality?/ freedom animation techniques and, luckily, I just was treating to add some little functionalities like that one a few months ago! So... although it is a WIP, you could give it a try carefully right now if you want:
fa-rl_meshinstance_03.0.3
Ah, if you finally dare, don't forget to examine the *.anme file to see how names convection works in this version! Cause, although I'm neither happy of how it works right now, I was treating to get more layer name flexibility been able to add a little numerical extension, that was when I just was treating to take up again my scripting learning, hence so much limitations, but well... then, I read somewhere that SynthSin75 still had done a better approach in this sense, so maybe an easy script "cross" could be quickly done if they fall in love... but I still had to finish my actual layer tool
* that is taking to me several weeks before I be able to think again in that cheesy things!
Well, of course good luck with your experiments! "But (with Dr. Filkenstein voice) curiosity kill the cat, you know..."
PS: I have just observed that curvature is baked for instance layers and, although it doesn't matter at all cause once instanced you can't manipulate'em anymore, I don't remember exactly the reason I did it in that way (I think it was cause real-time update issues), so I'll have to take an eye to that part too and see if the last Mike curvature access by script added can help...
* Tool that I guess you'll love as much as I still do, if you start to use masking (as it seems) as much as I do! Or I think so
