nhair dynamic and sine together?

#1

Hi!

I have a Rigging question which’s been bugging me for a while! Could someone help me please if you know how to solve this:

I’m rigging a kind of weird fish (a little sharky fish with a lantern) and I want his little fishtail to ondulate -so I added a sine deformer- but I also want my tail to follow the movement of the fish with an offset

In order to do that, I’ve been trying for days to use an nhair dynamic and a sine on the tail of my fish, however it doesn’t work very well… I wonder if it’s really possible to use these two functions together…
Have you got any idea of what I could possibly do to make it work?

Thank you in advance for your help! (and sorry for my clumsy english expression)

Regards

First, because I don’t know how much experience you have, are you aware of the importance of the order of operations in the history? It matters if you put the sine wave first or last after the dynamics.

Anyway, here is something that might help you. Duplicate the curve and leave it at the origin. Put the sine wave deformer on the curve which stays at origin. This way, the deformer acts on a nice straight version of the curve.

Then use that curve as a local blendshape (front of chain) to offset the dynamic curve. Sometimes separating things like this can help you see and debug what is happening easier than trying to combine it all in the rig.

Otherwise, you will have to post some pictures of the problems you are seeing to get better suggestions.

Thank you very much for your answer, it helped me a lot, I think I kind of managed to do what I wanted thanks to your advice!
Thank you again!!!
I really don’t have that much of an experience, I’m a beginner in Rigging but I’m doing my best to learn!
