Do you confused when you need to set up your rendering materials? How much you should set the opacity value, shininess, and the other values? Don’t be. AutoCAD (and other rendering software) has a template that define standard materials. All you need to do is select the type and template.
In this example, I use Realistic type, and Ceramic Tile, Glazed as template. After I chose it, all of my material properties value changes accordingly. It’s the common value for that particular material.
You may have to tweak it a little bit. But mostly it works fine. Every materials in my rendering here, was set using material templates. I didn’t change any properties at all.
This is not just in AutoCAD. I believe every application that renders have similar tool to this.
