IllusionCatalyst

IllusionCatalyst is a free instrument set designed to improve artistic expression and increase productivity in Autodesk 3ds Max. It consists of three independent scripts for specific tasks of the production pipeline.
IC.Shape Organic and hard surfaces polygonal modeling. Draw and erase mesh edges like on paper, deform and relax the surface like shaping clay by hands. Smart instruments perform complex tasks in a single action.
IC.Face Facial rigging and animation. Bring characters to life letting them express every emotion and mood with a full range of controllers. No more gummy faces allowed.
IC.Mime Keyframing and animation. Take a step and get the other one for free, control the flow of the action and each pose more easily. Forget about motion brakes.

Standalone development version of instruments included in IllusionCatalyst. A new idea goes through a refinement process by discussing its functionality with community artists, then it is integrated into the relative major script when is reasonably stable, bug free and mature.
IC.PolySplitRing Split edge rings with realtime preview.
IC.SizeInScreen Get and set a model screen appearance size in pixels.
IC.GeoEdgeLoop Refit closed edge chains to regular shaped polygons.
IC.FrameIt Help viewport navigation taking care of orientation and zoom factor according to geometry.
IC.ExtendSurface Extend an Editable Poly surface from its border with control of extension amount and slant.
