Individual Assets
In the Asset list you will find numerous included assets, which can be used to create both materials and polygonal objects.:
All assets are split into different categories. Note that you can add categories yourself with your own assets.
Note also that many Nodes in the different Node Editors - that themselves cover different function areas - work the same (e.g., Math Nodes) but other Nodes can only be used in the Scene Node Editor and have no function in the Material Node Editor. The Asset List is therefore filtered and only those Node listed that can be used in the respective function area.
