animating a single vertex on a spline
Hello and thank you to everyone who answers I’ve used this forum for many problems but this specific problem made me get an account.
I want to animate that single top vector, vertex, aka point to follow along the circle spline.
However the whole entire pyramid moves along with it and I don’t know how to restrain the bottom 4 points from moving.
I understand that I can do this by hand and move the point around but I’m sure there’s a way to make a single point follow a spline. So far I’ve enabled point level animation and tried doing it by hand, then tried to tie the point to a null but unsuccessfully.
thank you

You can do this with a very basic Xpresso setup: 11161_pointnode.c4d.zip

Adam,
How is the top point of the pyramid in the atom array linked to the Xpresso setup so as to accomplish what Ace is looking to do?
Thanks

the point node in Adam’s xpresso works with poly objects as well as splines, so you just have to feed the pyramid (it has to be editable) as the Object into the Point node (instead of the spline object) and in the Point node set the Point Index to the number of the point you want to follow (be forced to…) the Null’s position

Thanks Brian. That works great.

Thank you very much for this reply I’ve never touched Xpresso and this is the perfect gateway, you rock!
