setBlendingMode

Sets the blending mode of the PhysicallyBasedMaterial.

The blending mode determines how opacity and opacityThreshold are interpreted:

BlendingMode.OPAQUE: opacity is ignored.
BlendingMode.TRANSPARENT / BlendingMode.ADD / BlendingMode.FADE: opacity controls how the material blends with the background; opacityThreshold is ignored. Specifically, BlendingMode.FADE additionally fades specular highlights / reflections together with the surface alpha, while BlendingMode.TRANSPARENT does not.
BlendingMode.MASKED: opacityThreshold is used to clip pixels (alpha test) instead of producing semi-transparent results.

blendingMode

The blending mode to be used for the PhysicallyBasedMaterial.
