NEW IN R21
You will find the Node Space selection menu at the top right of the application window next to the Layout menu.
These settings were added because different renderers - in part incompatible among renderers - make nodes avaialble.
Assuming you want to create a Node Material for ProRender. Then you don’t need any nodes that only work with the Standard or Physical renderers in the Asset list.
In this selection menu you will find the following options:
The selection menu contains the folliwing options:
If you also take a look at any Node Material you will find a Standard option in the Node Space menu.
Here you can create a separate node setup per NodeSpace (=renderer) for one and the same material. The selected renderer will then use the fitting node setup, i.e., you don’t have to switch or re-assign materials when using different renderers with your scene. Of course, this only works if the respective renderer is supported, which Cinema 4D’s own renderers indeed do.
Node Materials that are not suited for the current Node Space will be marked with a warning icon in the Material Manager (and will be rendered black):
