    Properties

    mesh: SkinnedMesh
    modelMatrix: Mat4
    normalMatrix: Mat4
    material: Material
    jointMatrices: Float32Array
    previousModelMatrix?: Mat4

    Optional: world matrix from the previous frame, for per-object motion blur.

    previousJointMatrices?: Float32Array<ArrayBufferLike>

    Optional: joint matrices from the previous frame. Same layout as jointMatrices. When present, VelocityPass produces per-bone-accurate velocity; when absent the skinned mesh is treated as if posed identically last frame (no skin-driven motion contribution).

    morphDeltas?: GPUBuffer

    Optional: per-primitive morph-target deltas (vertex-major vec4 storage buffer from GltfMeshData.morphDeltas). Bound directly — owned by the model, never re-uploaded.

    morphTargetCount?: number

    Number of morph targets (0/undefined = no morph; the shader loop is skipped).

    morphWeights?: Float32Array<ArrayBufferLike>

    Per-target morph weights, length = morphTargetCount. Uploaded per frame.

    previousMorphWeights?: Float32Array<ArrayBufferLike>

    Optional: previous-frame morph weights, for the velocity pass.
