Seamlessly loop Wave Modifier in Blender
Seamless animation
For the Improviz gifs one of the requirements that Rumblesan set is that the gifs loop seamlessly. That is, one would not be able to tell where the gifs beings and ends. In Blender making an animation seamless is pretty easy. There’s lots of examples out there but for completion here’s my simple take on it.
With the default cube selected press I and then press on Location. This inserts a keyframe for the location (this menu can also be accessed in Object > Animation > Insert Keyframe). On the Timeline at the bottom move the animation 20 frames. Then, move the cube to somewhere else.
