R800ZZ WebXR PMX+VRM Viewer
3D avatar viewer, 3DCG video creator, VRM→ PMX converter

VRM → PMX conversion feature

Check the checkbox "VRM to PMX converter" and when you load a VRM file a PMX file will be produced.
This software performs conversions locally.
This software does not send files to external servers.
You can check the quality of the converted PMX avatar immediately after loading a VRM file, including facial expressions, physics, and motions.
I have worked to support loading as many VRM files as possible.
Known issue: elbows in VRM 1.0.

・VRM 1.0 conversion error (fixed)
・VRoid glasses not becoming transparent (fixed)
・Color differences on certain models (fixed)
・Other conversion errors (discovered errors have been fixed).

Video file creation

VR180 will be supported later.
For concatenating sequential image files, ffmpeg or an alternative software is required.
