Swirl teleportation effect

An effect to make objects appear/disappear in rings of swirling lights that follow the object's contours.

How to use: Just append the "swirl" node group, add a geometry nodes modifier to your object, and pick the "swirl" node tree you just appended. This effect works best with bloom enabled (glare node in blender 4.2+), but not with motion blur.

Options:

• Axis: The axis around which the swirls rotate.
• Velocity: The speed of the rotating swirls.
• Density: the distribution density of the swirls.
• Randomness: Gives the swirls random noise.
• Normal offset: 0 will make the swirling trails right on the object surface. Larger values will move them away along the surface normals.
• Lifetime: Larger lifetimes will lead to longer trails.
• Start frame: the start frame of the effect.
• End frame: the end frame of the effect.
• Base color: the base color of the light swirls.
• Color shift: Make the particles go through different hue variations on top of the base color.
• Fade out: make the object disappear instead of appear.
