cc cylinder, anchoring one end?
Hi guys,
a quick question, which I kind of think I know the answer will be no to, but is there a way of anchoring one end of a CC Cylinder in place while allowing to rotate the rest of the cylinder. i.e. I am finding it difficult to keyframe movement where I want one end locked in place and the rest of the tube rotating around that end, …CC Cylinder seems to translate around an anchor point that is in the centre of the cylinder.
Any suggestions or recommendations of other ways of creating a cylinder that is more controllable in this way would be gratefully welcomed.Cheers,
andrew

Not that I’ve ever been able to tell. However, you can precompse the cylinder’s content layer and move it around. That’s what I usually do.
Example: about the only thing I’ve ever used Cylinder for is to animate travel routes, especially flight paths. I compose the stroke or beam layer that represents the route, precompose it, wrap it around a cylinder in the downstream comp. I can roughly position the cylinder image and then go back upstream and start moving the route generator around till the endpoints are about where I need them to be. The anchor point position of the precomposed layer determines much about how it is positioned on the cylinder.
Hope you get additional advice, please let us know how you make out.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

I don’t know if this will help. The Anchor Point of the Cylinder’s rotation will still be in the center of the Cylinder (Radius-wise) but now it will be at the bottom, like a baseball bat that rotates from the hands holding it.
Take your layer that has CC Cylinder applied to it, and Precompose it, leave all attributes and Open. In the opened precomp, Ctrl K reveals the Comp Properties, double the Comp Height, say from 480 to 960, then slide the flat image up until it is at the top of the comp and it’s bottom is half way up the comp.
Now in the original comp, the precomp with CC Cylinder applied should rotate from the bottom of the cylinder.
Is that what you want?

thanks for the advice guys, yes the moving the texture halfway up the precomp did the trick (having the cylinder effectively be half transparent), moving the cylinder is SOOO much easier now that its apparent anchor point is at the end of the tube rather than the middle.
Thanks for the help!

Are there any video samples to illustrate your explanation for the cc cylinder pivotal point. Your description is not fully understood.
