Overview of Form Interface

This page gives an overview of each section of controls in Form. Make sure to read our What's New page to find out about new and improved features

The Form interface, as seen in the Effect Controls panel in After Effects.

Following is an overview of the parameter groups in Form.

  • Designer... button opens the Designer, which is an easy way to get started with Form. The Designer allows you to easily create complex animations by assembling (and tweaking) pre-made components.  Read the Designer pages to learn more about this powerful feature.

The Form Designer interface.

  • Base Form group defines the original particle grid – called a 'Base Form' – that can be affected by layer maps, particle controls, dispersion fields and every other control in Form.
  • String Settings (a subgroup in Base Form) enabled when you choose the Box Strings base form, and sets its size and basic appearance.
  • OBJ Setings (a subgroup in Base Form) enabled when you import an OBJ Model, and helps the base form to mold the shape of the OBJ file that it loaded.
  • Particle group controls the properties of the particles, such as size, opacity and color. This section also controls how the properties vary over the particles' lifespan.
  • Particle Type (a pop-up in the Particle group) sets the base shape of the particles.
  • Streaklet group (a subgroup in the Particle group) controls the Streaklet particle type, which can be used to create a long exposure, light painting effect.
  • Texture group (a subgroup in the Particle group) lets you select a layer in your Timeline to be the custom particle, and allows you to adjust the custom particle's behavior.
  • Glow group (a subgroup in the Particle group) controls the glow around the Glow Sphere and Star particle types.
  • Rotation group (a subgroup in the Particle group) rotates and orients the particles on any axis.
  • Shading group allows you to create shading on the Form particles.
  • Shadowlet Setting group (a subgroup in the Shading group) when the Shadowlet pop-up is set to On, this group is enabled which creates a shadow off the main light for soft self-shadowing.
  • Choose Name… button allows you to change the name of the Shadowlet Light, which is used by the Shadowlet Setting group.
  • Layer Maps group enables the pixels of another layer to control various aspects of the particles in the grid. The Layer Map subgroups include Color and Alpha, Displacement, Size, Fractal Strength, Disperse, and Rotate.
  • Audio React group lets you use audio tracks to affect the animation of the particle form.
  • Disperse and Twist group adds displacement by blowing apart or twisting your forms in 3D space.
  • Fractal Field group generates a Perlin fractal noise map in X, Y, and Z directions and over time.
  • Spherical Field group is used to push particles toward or away from a spherical volume.
  • Kaleidospace group adds 3D symmetry to the particle grid.
  • World Transform group lets you move around and rotate the whole particle system independently of the After Effects camera.
  • Visibility group allows you to obscure particles based on their distance from the camera.
  • Rendering group controls how the form looks when it renders.
  • Motion Blur group (a subgroup in the Rendering group) gives fast-moving particles a smooth look, like a real camera does.
