setOpacity

Sets the opacity of the PhysicallyBasedMaterial.

Valid range: [0.0f, 1.0f] (inclusive); values outside this range will be clamped to [0.0f, 1.0f] when applied.

Behavior depends on the current BlendingMode:

• BlendingMode.OPAQUE: ignored, the material is always fully opaque.

• BlendingMode.TRANSPARENT: 1.0f is fully opaque, 0.0f is fully transparent; specular highlights / reflections are not affected.

• BlendingMode.ADD: scales the additive contribution; the background remains visible even at 1.0f.

• BlendingMode.FADE: similar to BlendingMode.TRANSPARENT, but specular highlights / reflections also fade together with the surface alpha.

• BlendingMode.MASKED: participates in the alpha test against opacityThreshold instead of producing semi-transparent results.
