Note that not all of the material channels listed here are available for each material. For example, many channels will not be available for node-based materials. Inversely, many node-based materials have their own channels that are in turn not listed here.
Here you can enter a name for the object.
Surface color.
Irregularities in surface color (works by brightening and darkening the color channel).
Luminescent color (light-independent color).
Transparency (including refraction index).
Ability to reflect other objects.
Environment reflection (simulates reflection).
Fog effect.
Virtual bumps on a surface.
Use this setting to activate the Normal material channel for optimized virtual surface unevenness.
Defines the localized texture invisibility.
Defines the halo around an object.
Defines the authentic bumps on a surface.
Here you will find several settings pertaining to the view (texture size, tessellation, etc.).
This tab displays custom material channels you create. More information can be found here.
This is where you will find all settings relative to Global Illumination mode.
Click on this button to create a custom channel.
Materials assigned to an object will be listed here. Alternately, an object can also be dragged and dropped into this field.
Node-based materials have this button with which you can open the Node Editor.
Node Space
As described hier, a Node Material can contain different Node setups for different renderers. Depending on which renderer or Node Space is active, corresponding Node setups will be displayed and evaluated.
Here you will find those renderers listed that can work with Nodes: ProRender and Standard / Physical renderer (since S22). If you have 3rd-party renderers installe, these can also be listed here if they are compatible with the Node Space system.
Each renderer has a button, which is either
- Add: no Node setup has been created for this Node Space, yet or
- Delete: a Node Setup already exists for this Node Space.
If you click on Add, a default Node setup (i.e., exactly what is created if 
New Node Material
The Node setups for different Node Spaces are clearly separated and are not compatible.
Be careful when deleting because you can end up removing complex Node setups.
