    Protected_renderManifest

    _renderManifest: RenderManifest | undefined = undefined

    Cached render manifest to avoid frequent allocations.

    color: Color

    The base color of the material.

    cullMode: CullMode = CullMode.DEFAULT

    The culling mode for this material. Defaults to BACK.

    deepWaterColor: Color
    depthTest: boolean = true

    Whether the material performs depth testing. Defaults to true.

    depthWrite: boolean = true

    Whether the material writes to the depth buffer. Defaults to true.

    edgeColor: Color
    edgeSoftness: number
    foamColor: Color
    foamCutoff: number
    foamDistance: number
    foamNoiseScale: number
    foamNoiseSpeed: number
    refractionStrength: number
    speed: number
    time: number = 0.0
    transparent: boolean = false

    Whether the material is transparent. Defaults to false.

    type: string

    The type of the material.

    uuid: string = ...

    The unique identifier of the material.

    waterAbsorption: [number, number, number]
    wave1: [number, number, number, number]
    wave2: [number, number, number, number]
    wave3: [number, number, number, number]
    inspector: Record<string, InspectorField> = ...

    Fields common to every material, merged with a concrete subclass's own inspector map (e.g. StandardMaterial's metallic/roughness) via collectInspectorSchema().

    Protected_createBaseManifest

    Protected_getLiquidWaveShaderSources

    • _getLiquidWaveShaderSources(): {
          glsl100?: { fs: string; vs: string };
          glsl300?: { fs: string; vs: string };
          wgsl?: string;
      }

      Vertex/fragment source per backend -- the only part that differs between presets.

      Returns {
          glsl100?: { fs: string; vs: string };
          glsl300?: { fs: string; vs: string };
          wgsl?: string;
      }

    Protected_syncBaseManifestState

    Protected_syncTexOffsetRepeat

    • _syncTexOffsetRepeat(
          tex:
              | {
                  offset: { x: number; y: number };
                  repeat: { x: number; y: number };
              }
              | undefined,
      ): void

      Helper to synchronize texture offset and repeat from a given texture.

      Parameters

      • tex:
            | { offset: { x: number; y: number }; repeat: { x: number; y: number } }
            | undefined

      Returns void
