AlphaMode

OPAQUE

The material is completely opaque and doesn’t use the alpha channel. This means that the alpha value is ignored, and the material is rendered as fully opaque.

TRANSLUCENT

This mode uses the alpha channel to blend the material with the background, but doesn’t write to the depth buffer. As a result, it is rendered last to ensure correct blending.

MASKED

In this mode, the alpha channel is used to decide whether a pixel is completely opaque or transparent.

ADDITIVE

This mode adds the RGBA channels together. Note that additive materials don’t write to the depth buffer.

NONE

The material is completely transparent and doesn’t affect the rendering output.

TRANSLUCENT_POST

The material is completely transparent and renders the material late in the render process.
