Process of converting a self-made virtual character (other than a humanoid) from an FBX file to a VRM file so that it can be used in a metaverse such as cluster ①

System requirements: Windows 11
Unity version: 2021.3.9f1
Blender version: 3.2

★Here is the character to use (called Amanyu).

★The state before exporting with Unity/Blender is here.

★This is the state after the import in the cluster.

This is what I had already finished at the time of the FBX file.

・Amanyu modeling, sizing, rigging, skinning, motion in action, UV development, textures, and material creation.

★ Here is what I did with Blender when converting to a VRM file.

・Introduction of add-on Rigify

・Convert from action motion to shape key

★ Here is what I did with Unity when converting to a VRM file.

・Introduction of UniVRM

・Material settings

· Conversion to Humanoid + T pose setting 　← Personally, this was the hardest part.

・Linking shape keys to blend shapes after converting VRM files

From here, I will describe a simple flow, and I plan to explain the detailed settings in pixivFANBOX.

Below is a simple flow.

① Install UniVRM from GitHub

Good job 24 hours GitHub !

②Introduce Rigify in Blender and add Human armature

→ Export to Unity as FBX file

→ Convert AnimationType of Rig to Humanoid

→ Set T pose in Configure

Make sure you have the required bones

By the way, this is what happened when I applied the bones appropriately without installing Rigify.

③ After selecting the action motion bone in Blender, export the model saved as a shape key as an FBX file

→ After importing to Unity, set various materials (manipulate shaders and values)

→ VRM file conversion

→ Import to Unity again VRMBlendShapeProxy After selecting BlendShape, tweak various values and register

Kawaii Amanyu

④ Uploading to cluster: If there are no missing bones, etc., it should be possible to upload without any problems.

Arrived at the cluster safely and smiled Amanyu

★ As a result, I was able to convert my self-made virtual character (other than humanoid) from an FBX file to a VRM file and use it in a cluster!

However, there are still some problems, such as the following, so I would like to improve it in the future.

・When hair (oil) overlaps a specific object, it becomes transparent

・Actions such as hand gestures are not possible
