Function createResourceIconMaterial

createResourceIconMaterial(
    descriptor: ResourceDescriptor,
    icon?: Texture<unknown, TextureEventMap>,
    opts?: { depthTest?: boolean; occludedPass?: boolean; strength?: number },
): ShaderMaterial
Camera-facing icon material for one resource type.

The quad is billboarded in view space — the instance matrix contributes only its translation, and the corners are pushed out along the view axes — so icons stay legible from every camera angle without any per-frame CPU work.

Fog is read from the same FogData texture the terrain samples, through a per-instance cellIndex attribute, so an icon follows the memory tiers its ground does: hidden while unexplored, dimmed once explored but out of sight, full strength while visible.
Parameters
- descriptor: ResourceDescriptor
- Optionalicon: Texture<unknown, TextureEventMap>
- opts: { depthTest?: boolean; occludedPass?: boolean; strength?: number } = {}
  - OptionaldepthTest?: boolean
    Disable to draw over occluders instead of being clipped by them. Default true.
  - OptionaloccludedPass?: boolean
    Build the ghost pass: reverse the depth test (GreaterDepth) so the material draws only where geometry occludes it. Pair with strength.
  - Optionalstrength?: number
    Alpha multiplier — the ghost pass's dimming. Default 1.
Returns ShaderMaterial
