Node material question

I’m new to node material, I’m seeing examples in playground, I can see the alpha and opacity change for one node, it applies node material to it, but I can’t see any alpha and opacity change for that node in inspector, could someone explain about this? And is it possible to get the opacity of current node?

Hello the alpha value indicated in the inspector is a variable defined at material level for all pixels.
Node Material are generating shaders and thus the alpha value can be changed per pixel.

In a nutshell, the value displayed in the inspector for standard or PBR materials is not used by a Node Material as Node Materials are using a different way to deal with opacity
