Kevin, I was hoping to avoid having to make morphs for movement of the snake. There is a lot of movememt involved that should be done with IK but I'm not sure how. I have remade the snake(it used to be one segement with a spline-many problems) as a series of linked balls in the shape of a snake. It allows me to pull the head around I am still experimenting with IK. Sanford

Sanford- Here's another thought – create the snake as two figures : the head and the body/tail. This will allow you to create a single action of the body moving about, and another action for the head rearing up, attacking, etc… Heck, if this works, you may even create a third figure of just the tail if it's a rattler. Then you can create an action of the shaking tail. Let me know if that helps, -Kevin

A thought for the snake: you should be able to use a channel to _draw_ the the slither path, then send the snake model sliding down it. Think of a flexible plastic strip stuck in a wavy groove. Hmm… Gavin.

Hmm… This sounds like a great solution. Could you go into some more detail about how you set a channel up to make the snake bend within the "groove".

Could you go into some more detail about how you set a channel up to make the snake bend within the "groove"." I _told_ everybody I only make suggestions so other people will figure out how to actually make them work! :> I was thinking of a channel in Action, representing changing values for the X and Z coordinates of each (constrained and skinned) segment of the snake figure. Each segment would move through each point in the channel in a different point in time. Try it first with a cube or something, then two, just to see if the concept works. Gavin.
