About Random Roller

Random Roller is a script for After Effects that introduces controlled randomness into layer management. It can randomly select a subset of layers in the active composition, assign selected or deselected status, and use a re‑roll feature to narrow the selection. Users can invert the random selection, randomize the order of layers, or randomize the order in which layers are selected, supporting the Quick Offset workflow. The script also sorts selected layers into a user‑defined number of groups; each effect‑capable layer receives a Slider Control reflecting its group number. Optional features include applying label colors to groups, prefixing layer names with the group number, and adding comments to each grouped layer. Dedicated buttons allow selection of a specific group or adding a group to the current selection. Random Roller runs on After Effects 2026, 2025, and 2024, with the latest version 1.1.4 released on April 2, 2026.
