BVH PMX VRM Converter

About This Tool

This tool provides cross-format interoperability for motion and avatar data among BVH, VMD, PMX, and VRM. It targets 3D artists, game developers, studios, and pipeline engineers who port or re-author animations across tools. Use when importing motion data from one format into another, porting PMX-based characters to VRM, or retargeting BVH motions to VRM avatars. Core objective is to preserve bone hierarchies, animation curves, and morph targets while adapting data to the target format constraints.
Two-step conceptual flow: first, parse and normalize the source data into a generic internal representation; second, map bones, axes, and animation curves to the target conventions and export a clean file. This ensures compatibility across tools like Blender, Unity, and Unreal. The tool benefits modelers porting assets between platforms, VRM creators delivering avatars for apps, and studios delivering asset packages with consistent animation pipelines. Unique value lies in automated bone-mapping presets for popular rigs, batch processing, and a validation log that highlights missing bones or incompatible morph targets. Core features include format parsing for BVH, VMD, PMX, VRM; a generic representation; axis remapping; scale handling; batch jobs; and an output integrity report. Use cases include porting BVH motions onto a VRM avatar or converting a PMX character rig to VRM for game engines.
