vastSolver 2

vastSolver 2

Mac OS, English

Convert vertex animation to skin weights and joints. The main use is to compress mesh animations, such as a blendshape-driven animation or a cloth/muscle simulation, for use in the game engines.

General Usage Instructions

The vastSolver can be used as (1) a compact GUI tool or (2) an Autodesk® Maya® command. 

In the GUI mode, the user has to select a target mesh and set solving parameters. If the mesh animation is suitable for the solving, the tool will solve and set up mesh and joints (with "_vast" appended to the mesh name) in the scene. 

The Maya command vast is provided. The command flags are the same as the parameters displayed in the GUI. 

There is a User Guide that contains the command documentation.
