Attn: VRM Live Viewer users,
VRM Live Viewer (by Fantom-san) is a free software playing back BVHs, VMDs, and/or preset motion for VRM models.
If you are prepareing a VMD file for VRM Live Viewer playback,
- (1) Download ZIP for "VMD twist motion separator set for Unity-based VMD players for long sleeve models",
- (2) Extract all the files from the ZIP file,
- (3) Drag-and-Drop an original VMD (MMD motion) file onto VmdTms.exe,
(then the converted VMD (xxxx-cnv.vmd) will be generated,)
- (4) Drag-and-Drop the converted VMD onto VRM Live Viewer.
--
Please be sure to keep the license condition as directed in the ReadMe attached with the VMD.
Most of the VMDs require credit notation to fullfill the series of the license inherited from parent works.
--
If you like to playback more accurate motion compensated for the bone angle difference between the original model and your model, also use "VMD Retarget" to correct the difference beforehand. (In that case, first use VMD Retarget, and then use VmdTms.)

--
Drop the source model file (PMX/VRM) onto learningSoucePMX/VRM,
drop the target model file (PMX/VRM) onto learningTargetPMX/VRM for learinig their bone angles and position,
and then drop the VMD file onto VmdRetarget.exe.
The converted motion VMD (***-ret.vmd) will be saved automatically in the same folder as the original VMD.
--
Fully-captured motion set supports BVH/VRMA read-in.
(Three-step conversion: first drop the Target model (PMX/VRM) onto learningTargetPMX/VRM, next drop the BVH/VRMA file onto learningSourceBVH/VRMA (=>a pre-converted VMD file will be generated), and then drop the pre-converted VMD file onto VmdRetarget.)

Standard set for VMDs using Leg-IKs. For application using UnityVMDPlayer library (by hobosore-san), such as VRM Live Viewer.
VMDTMS set for Unity-based VMD players for long-sleeve models (for FK motion), vmdtms121i8expt-longsleeve-vrm.zip (648kB)
for FK-based VMDs (that does not use Leg-IKs). Mismatch correction of up-down body motion is supported for the FK.
VMDTMS set for Unity-based VMD players for long-sleeve models (IK-off version), vmdtms121i8ikoff-longsleeve-vrm.zip (648kB)
for VMDs that have both FK- and IK-based Leg motion. This set disables the Leg-IK to enable the FK playback.
VMDTMS V1.16-compatible conversion set (learningposePMX set), vmdtms121i8set-compati116.zip (1390kB)
for use in native MikuMikuDance (MMD). This set relaxes strong arm twisting to avoid arm squeezing as possible.
VMDTMS full-arm correction set (learningposePMX set), vmdtms121i8set-learnandtune15.zip (1390kB)
for use in native MikuMikuDance (MMD). This set reproduces most natural human arm movement with the twisting motion.
VMDTMS set for Mother-bone motion mixing, vmdtms121i8-motherbonemix.zip (443kB)
The Mother-bone motion will be mixed with Center bone and deleted, which allows users using VMDs without editing PMXs.
VMDTMS set for bone/morph listing, vmdtms121i8-bonelist.zip (444kB)
This set is for generating a detailed list file (list.txt) of bone/morph names.

Drag-and-drop a VMD file onto VmdTms.exe to start conversion.
(If the set includes learningposePMX.exe, first drop the PMX file onto learningposePMX, and then drop the VMD file onto VmdTms.)
