About MoleculeGen°
MoleculeGen° is an Adobe After Effects extension that creates detailed circle‑pack shapes and animations, supporting both flat 2D graphics and 3D compositions. Each circle can be adjusted individually for position, rotation, fill, and stroke. Batch placement lets you manage multiple layers and groups, with settings for uniform circle size, total count, and batch size. Over 200 color themes and adjustable extra strokes are included. For 3D work, the plugin provides dedicated parameters and an extrusion option that require the Cinema 4D renderer to be enabled. Compatibility spans After Effects CC 2019 through the 2024 release, and the last update was in June 2024.
