1. A computer-implemented method for generating a behavioral component of an animation asset that is stored for future execution, the method comprising: attaining the animation asset including the behavioral component by reading animation asset data from at least one file stored within one or more memories; generating an executable representation corresponding to the behavioral component based on a virtual machine (VM) instruction set architecture (ISA); generating a transport file comprising the executable representation and a geometric object that is configured to be animated when the executable representation is executed; and evaluating, using the transport file, a scene description on a first platform distinct from a second platform which generates the transport file, wherein the first platform and the second platform include respective runtime engines that support the VM instruction set and are developed from different source platforms, wherein the behavioral component includes an animation rig describing how movable components of a geometric object move to simulate actions by the geometric object, and wherein the animation rig includes steps for transforming input parameters to output parameters.
