If you don't want rotation but instead a more linear movement, you can add a second mapping node in front to offset the origin and thus offset the point of rotation. If you use these coordinates to generate noise and animate the z rotation, the noise will be rotating about your object. Using a Mapping node, we can rotate the coordinate space. Right now they both have Object Coordinates showing. I have a sample scene here with a large plane that is just meant to show how the coordinate plane is moving, and a cube representing your object.
You can use a 3d texture and animate the movement of the coordinate space. I think it's better than cluttering this page with gifs.
With a sufficient number of "channels" of animation, perhaps rotated or scaled differently, you should be able to create an animation where the fade of one channel is obscured by the activity of the others. Select these nodes and duplicate them, and then you can G + X Grab all of the newly created nodes' keyframes in the dopesheet and Constrain to the X-axis to offset the animation timing by a number of frames. This method isn't perfect for everything, but perhaps it will get you started.Ĭreate a segment of animation of the length you desire, where the effect fades in, runs for a length of time, fades out, and the parameters of the animation are reset to the beginning values while invisible.
