Flexible Layouts for your Layers

Flex is a tool for creating dynamically realigning layouts for your layers in After Effects.   Flex Line Rigs focus on single rows or columns, while Flex Grid Rigs handle more complex scenarios comprising several rows or columns working as a cohesive system.

Flex is a collaboration between Vincent Raineri & Zack Lovatt


Flex Lines

A Line Rig will connect all of your selected layers together into a straight line.

Then you can quickly & easily have the size of one layer affect the scale and position of its neighbours, creating a nice flexible line.

Flex Grids

If a Line Rig is too 1-dimensional for you, try a Grid Rig!

Flex Grid Rigs will take your existing layouts and create horizontal and vertical controllers for them, letting you dynamically flex groups of layers as rows and columns.

Flex Methods

Once rigged, Flex gives six different ways to handle scaling within your layers.


Flex Mattes

Don’t want to mess with your layer scaling? Try Flex Mattes.

Instead of modifying your layers, Flex can create rigged mattes, preserving your art & still getting all perks.
