Shaders Overview/VehicleShader/MotionPathRubber

Motion Path Rubber

This shader variation, known as Motion Path Rubber, is tailored for rendering static rubber or metal mesh tracks and belts, such as those found on crawler vehicles in farming simulations. The shader utilizes a vertex animation texture (VAT) that contains predefined poses, allowing for the simulation of track and belt movements like advancing or retracting. These poses are created from spline data in Maya or Blender, processed by a custom tool, and then exported for use in the GIANTS Engine. While the animation is not responsive to environmental interactions, it effectively simulates the mechanical movement of caterpillar treads in a pre-determined, looped sequence.
