blendOption
Determines how primitives in the collection are blended with the scene. Must be BlendOption.OPAQUE or BlendOption.TRANSLUCENT; BlendOption.OPAQUE_AND_TRANSLUCENT is not supported.
BlendOption.OPAQUE disables blending and writes depth, so primitives occlude each other and the geometry behind them. BlendOption.TRANSLUCENT alpha blends primitives and does not write depth, so they are resolved by order-independent translucency instead.
