2 Set up VRM¶
VRM Model¶
In the previous section, we have introduced how to convert a Humanoid 3D model to VRM
First drag and drop a VRM file (~.vrm) into the Assets folder. The prefab file associated with the VRM file can be automatically generated.
normalized
Click the prefab file (normalized model) and check the inspector window. As seen in the image below, components such as
VRMMeta,Animator,VRMBlendShapeProxy,VRMFirstPerson,VRMLookAtHead,VRMLookAtBoneApplyerare attached to the model:
Open VRM prefab in the scene¶
File - New Scene
prefab をシーンに展開します。
Create a new scene by File - New Scene or use an existing one, then drag the prefab file to the Hierarchy window:¶
By clicking the prefab’s GameObject in Hierarchy, the VRM model’s information will be displayed in the Inspector window. Note that **spring bone settings can be found in the GameObject named secondary **. Also, in VRM Meta, make sure title, author, license (the most important one) are set.
To make a VRM model fully functional, please set up the following components:
Expression and lip-sync (BlendShape)
First-person settings (Exclude model’s head in first-person view for VR applications)
Eye gaze movements controlled by bone or BlendShape
Spring bone (SpringBone/SpringBoneCollider)
Export VRM model again¶
After the all settings are completed, select the the model (topmost parent GameObject) in Hierarchy and again export the model from VRM0 -> Export UniVRM-0.XX.
vrm_menu¶
Previous versions: VRM -> UniVRM-0.XX -> Export humanoid.
UniVRMExportHumanoid¶
Pose Freeze
Pose Freeze is for model normalization during export. The exporter will automatically check whether the export target needs to be normalized.
For instance,
in Hierarchy if a mesh’s rotation or scale is not Default (first VRM export or adding accessories to the VRM model), the model normalization needs to be performed.
Other settings such as Bake BlendShape State is also available.
Done！¶
Your VRM file is good to go. Try to import the VRM file into applications that support VRM!
