So, the Curve tool is an essential feature for a great many activities.
Among many other things, once you have a curve defined, you can render a
brush along it.
Now we also can render that brush even when it contains an animation,
i.e. it is an animbrush. It can render into the current single image, or
it can be animated to render as animated brush into each frame of an
animation. (look for that in the More... options. When rendering it into a single image, this can be on demand in the Finish section, or automatically, when configured to auto-stroke or auto-draw the brush into the newly stroked curve's path.
An animated brush is essentially one wich has not just one image loaded
but a bunch of them. Sometimes they are random images without
correlation, on purpose. Sometimes they are sequences of a very precise
type. Such as a looping walk sequence that you rendered from Poser, DAZ
Studio or other 3D programs, or that you draw by hand, or even coming
from real video footage.
When the brush is an animbrush, it renders along the curve and
constantly updates and advances to the next frame of the brush as it
renders into the current still image. Or even when rendering into an
animation. Now you can make those animbrushes come to life in a new
animation through the Curve tool.
Below you will (re)discover some great ways with the Curve tool.
