hi all.
I need to animate a dolphin but im very far to be a pro at rigging/animation.

the best would be to control the spine and tail separatly. to be able to curve only the tail and vice versa.

i wanted to watch the video about bone / pole item etc here http://www.newtek.com/lightwave/96training.php
But the video seem to be broken.
can someone help me please!

i attach the bone structure of spine and tail if needed

thank you very much

The video works on my end.

I would recommend finding where the "hips" of your dolphin are and using that as the origin if your tail and spine. I loaded up your object and you have the bones starting at where the nose is. This makes it really difficult for you to do any back and head animation independent of what your tail is doing.

thank you all for your advice. for example, if i use deformation with splne like spline shift transform plug in, i cannot animation the tail and it seem very rigib animation.

it is possible to make thing like that?

with sine waveform displacement maybe?

For anyone else wondering, those videos do work but they take forever to load. Been like that on my end for a while. Not sure what the deal is in that other sites work fine. My workaround has been to just download them.

I would suggest PLG's Curve IK instead of spline shift.

In terms of getting the sine wave motion that just comes down to keyframes and timing.

I think that the best way to animate a Dolphin is with IKBoost. This would be very simple using the handle feature. It also has all the benefits of saving poses and animations. Look for the tutorials from splingod. He has the most in depth training on the matter that I have seen.
You could also go to Youtube and type in IKBoost and find many other training there.
Good luck.

You can also have wind forces affecting the bones with IK booster applied, and I think you can use a directional wind and use the velocity vectors with a procedural animated texure for the motion.

Proton has a video of some of that with IK booster applied.

You could do a little research about using relativity and expressions too.

thank you very much all. i cant use correctly PLG curve Bone. if i put more than 3 null in the plg curve bone top, my dolphin goes crazy when i try to move it to the 4th null, it is normal?

i havent tried Ik Boost. i will watch today. my firewall block access here.

Post the lws file.

here the scene. i made a really simple scene with a master null. a goal and some control point for the spline ik.

Maybe i dont know how to use plg curve. but when i try to move the master to the rear . bone ges crazy. how do you think?

If you're trying to create a setup like that you could use the morph through bones trick instead.

it was an example, but i need to control my curve, with this kind of curve. do i made a mi stake in my setup that cause the bone problem?

there's nothing wrong with your plg curve setup... but you're misunderstaning what plg curve does...

its a spline IK modifier, not a spline motion path. The reason your bones flip backwards when you move the chain forward fo the controllers is because they're reaching back to the controls that are now behind them.

Thank rebel !

i understand now. so if i need to move my dolphin i need to animate my control point on Y axis and control general move by a null parents?!

ok. its a little scene test , its far from perfect but i understood the concept. THANK YOU ALL!

here the scene for the people who , like me, dont understand some plg plug in.
