    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This plugin consists of two tools: PoseWrangler and Pose Driver Connect.


PoseWrangler is a Maya Python tool for interfacing with the MayaUERBFPlugin. The RBF plugin allows users to author complex secondary animation in Maya leveraging a driver/driven relationship to smoothly blend between n number of poses or transformations.


For example, to fix problematic areas of deformation like shoulders, elbows, thighs and knees you can create a list/set of poses and tweak the secondary joint transformations to fix the deformations in each pose.


PoseWrangler provides a Python API and user interface to simplify the creation/management of RBF setups and export the RBF data to intermediate files that Pose Driver Connect can read inside Unreal.


Pose Driver Connect is a C++ Unreal plugin that can take the exported data from PoseWrangler and create a network of PoseDrivers in an existing AnimBlueprint which results in secondary deformation that is a one to one match with the deformation authored in Maya.
