# BlendingState

#### BlendingState()
Scene/BlendingState.js 21

The blending state combines `BlendEquation` and `BlendFunction` and the `enabled` flag to define the full blending state for combining source and destination fragments when rendering.

This is a helper when using custom render states with `Appearance#renderState`.
