3D Artist Guide
Whether you create Live2D or 3D characters, your rigged models can be used on Hologram.
Steps
- 1.
- 2.Animate your 3D model using blend shapes or skeletal animations (Optional).
- 3.
- 4.Use your character model on Google Meet or Discord through the Hologram Chrome Extension.
Requirements (3D)
- 1.For rigging, you need to follow the Apple ARKit blend shape naming convention. More on this in the "Rigging (3D)" link below, under "References".
- 2.Export your 3D model as a .gltf or .glb file.
Our Chrome extension supports 3D characters in glTF format and Live2D characters in Live2D Cubism's standard file types. We will soon support VRM and FBX formats as well.
Our real-time face tracking follow the blend shape naming convention of Apple ARKit. However, not all blend shapes need to be created.
Hologram has a tier system for the ARKit blend shapes. Tier 1 consists of the baseline coefficients that the character models should have to be functional. Tier 2 and 3 consists of blend shapes that would make the character models a lot more expressive.
Tier 1: eyeBlinkLeft, eyeBlinkRight, eyeWideLeft, eyeWideRight, jawOpen, mouthSmileLeft, mouthSmileRight
Tier 2: eyeSquintLeft, eyeSquintRight, mouthFunnel, mouthPucker, mouthFrownLeft, mouthFrownRight, mouthShrugUpper, mouthShrugLower, browDownLeft, browDownRight, browInnerUp, browOuterUpLeft, browOuterUpRight, noseSneerLeft, noseSneerRight
Tier 3: cheekPuff, mouthLowerDownLeft, mouthLowerDownRight, mouthUpperUpLeft, mouthUpperUpRight, mouthLeft, mouthRight
Our full-body tracking follows the naming standard below.
The easiest way to test out your Live2D or 3D character model against Hologram's facial tracking system is via our web studio.
