Reasonably new to C4D and I'm having a weird issue using a Memory Node.
I have an object (a butterfly) which I've animated so that it's wings flap.
In order to save on keyframes, I've set up a Null object which I've connected through Xpresso to drive the wings. I've also used the same Null to drive the position of the body as well as a bend deformer so that I have a nice natural bend in the wings.
In order to achieve natural looking movement, I've set up a Memory Node between the Null and the body / bend modifier which delays the effect of the driver. It all looks great in the Editor window, however when I render to picture viewer, the Memory Node has no effect at all.
