Alembic Cache
Alembic Cache is a tool used in special effects and animation to save and store complex 3D animations efficiently. Think of it like taking a snapshot of moving 3D objects that can be easily shared between different animation software. It's especially useful when working with detailed visual effects like explosions, cloth movement, or character animations. This method helps artists and studios save computer processing power and makes it easier to share work between team members. It's similar to saving a video of a 3D animation, but in a way that still allows some editing afterward.
