Fish rig
show user profile  Master_Soda
I am working now on this model :

all the maps are done and the bones are in place, the only problem is I don't know how to make them work right , that's how it looks :

description (in case I not doing it right):
there are a spline constrained to the bones,the red helpers are constrained to the spline and the small bones constrained to the red helpers, the skin goes on this bones.

Spline is the way to go. Having said that, it's very tricky. I swear I provided you with links to CG Academy's rigging a spine tutorial. Youtube it, there's SOOOO many steps to getting it right, I don't think you'd get all the answers here.

Of course, if there's an easy way to do it without a spline, I'm pretty interested.

yes I watched the parts 1,2 and 3 from the link you provided me.


but what I am asking about here (forgot to mention) is how I can make a bone folder to both sides L\R and not up and down .
when I used HD solver it seemed to be working but I couldn't move the whole thing without messing everything , High IK doesn't work so now I use IK limb solver but stil I don't get what I need from it.

Tricky. I think it's something about setting your upnode of the bones. If you go to Character -> Bone tools, and turn on front fins you'll see which way your bones are orientated. You'd want the front fin to be pointing left or right. Here's some pics:

Now set an HI IK solver (BTW "HI" stands for history independent). Make a dummy and align it to the same height as the IK. Then...

Just remembered. I rigged a fish a while back and got it's tail to animate pretty quickly

Bad news first: Delete your rig.

Good news: CAT has a lizard preset for one of it's CATParents. Delete the arms and legs and you've got a pretty handy fish rig. Pose it and skin it.

Really good news: You can set up a "Walk Cycle" to make the tail animate how you like automatically.

[edit] You have to choose the "marine" preset found under CAT rigs, or something like, that to get the tail controls. Look around, you should find it.

Its too late for that , made it work with bones and splines not so successful but it works.
only one little problem , used a custom parameter for the swivel angle and it doesn't get key frames,
may be I should keep CAT to the next model , I am think maybe I should make a cat.
