Apply glossy and transparent shaders to objects
Use multiple materials for the same object
5.1 Adding materials to objects
Any scene in Blender can benefit from a combination of good lighting
and realistic materials. With the materials tab, you have plenty of tools
and options to assign shaders, textures, and other effects to give visual
context for surfaces.
For instance, if you have to create a 3D model that should appear as a
stone wall, you can use a texture on that object to make it look like a
stone wall. We can create all types of surfaces based on a combination
of shaders, effects, and textures.
Before we start to handle material creation and shaders, it is essential to
define a few aspects of materials in Blender:
A material must have one or multiple objects assigned.
You can remove a material from an object. If a material doesn't
have any assigned objects, Blender will purge that material when
you save and close the project file.
Multiple objects can use the same material.
Each material must receive a unique name that will help you
identify what it represents visually.
You can reuse materials in other projects using the Append or Link
options from the File menu.
