Hello @ecojust , how are you doing?

Here is a working Playground.

PBRCustomMaterial-Alpha | Babylon.js Playground

You must set a value for material.alphaMode and material.alpha. You can check what the effects will be based on the alphaMode in the following documentation: Introduction To Blend Modes | Babylon.js Documentation

oh, thank you very much.
In fact , i have tried that before , but my code is different with you

    material.alphaMode = 2;
    material.alpha = 1;

or

    material.alphaMode = 2;
    material.alpha = 0.5;
