Create VRMA Animations

Create VRMA clips with Blender and the VRM Add-on for Blender, then use those clips in Desktop Homunculus MODs.

This page is a workflow guide, not a full DCC tutorial.
For exact UI operations, always follow the latest official Blender and VRM Add-on documentation.

What This Page Covers​

  • A recommended authoring workflow for VRMA clips
  • How to move from DCC authoring to HMCS asset usage
  • Where to verify playback after export

Use Blender + VRM Add-on for Blender as the default path for VRMA authoring.
This workflow can include facial expression tracks in the exported animation clip.

Before You Start​

  • Prepare a VRM model that you will animate.
  • Keep source files versioned so you can iterate safely.
  • Verify licenses and redistribution terms before packaging assets.

Set Up Blender and VRM Add-on​

Goal
Install and configure the authoring environment for VRM-based animation work.

Use official docs

Expected outcome
Blender and the VRM Add-on are installed and ready for importing a VRM model.

Create Animation Clips and Expressions​

Goal
Author skeletal motion and expression tracks in your DCC scene.

Use official docs

Expected outcome
Your scene contains a reusable animation clip with the motion and expressions you want to ship.

Export as VRMA​

Goal
Export your authored clip into VRMA format for runtime playback.

Use official docs

Expected outcome
You have a .vrma file ready to register as an HMCS asset.

Verify in Desktop Homunculus​

Goal
Confirm the exported VRMA behaves as expected in the runtime environment.

Use official docs

Expected outcome
The animation plays correctly on your target character, including expected pose and expression behavior.

Use VRMA in Your MOD​

Register the exported .vrma file in your MOD's package.json and play it from the SDK.

Troubleshooting and Updates​

  • If export or playback behavior differs from your setup, check the latest Blender and VRM Add-on docs first.
  • If results differ after updates, re-check export options and rerun runtime verification in HMCS.
