Absolute Character Tools: Modeling Tools Set (or 'ACT-MTS' for short) is a sophisticated musculature system for 3ds max™ that helps you add extra realism and believability to characters that you create. ACT-MTS gives you several new object classes for modeling muscles and skins and also has a whole skin deformation technology that does both sub-skin deformation and in-skin deformation. It is extremely fast, stable, customizable, and open for scripting and wiring.
Central to ACT-MTS are its cgMuscle and cgTube primitives. These are the fundamental building blocks for creating muscle rigs and deforming the skins of your characters. In contract to its big brother (ACT 1.6 Pro), ACT-MTS is strictly designed for the serious modeler. The cgMuscles and cgTubes do not animate over time like it's sibling, however the musculature rigs will fully deform the overlaid skins on a single frame, making it an effective addition to your modeling arsenal. You can pose your characters on a single frame with deformation intact through the cgMeshDeformer(static), and then you can use the Sub-Object attributes of the cgMuscles to further refine and enhance the look of your models. |
