What is a(n) CAL file?
A CAL (3ds Max Pose Adjustment Format) file is a scaleable pose adjustment format used by Autodesk 3ds Max, a 3D modeling, animation and rendering application. It stores per-vertex information about skeleton transforms so the weights of each vertex to its associated control point can be adjusted in 3ds Max. This allows users to fine-tune deformation of meshes and increase realism of motion-captured data.
CAL files are commonly used for video game character animation, rigging and special effects. They can also be imported into compatible programs from other companies, allowing users to create cross-platform animations.
