The right part of the screen will always be occupied by the Info panel. It shows a general view of the organization of the scene:
Located in the top section, it contains two of the most important panels in modo: the items list and the shader tree.
The Item List panel is the panel that will show you general information about the scene. It contains the list of layers that make up the scene as well as other basic items.
By default, in a newly created scene, it contains only one layer, a camera item, and a light item (a Directional Light by default). For a reference, you should have in mind that mesh layers in modo are the same as objects in most 3D packages.
The Shading panel is essential during the material/texturing phase. It contains in-depth information about the various shaders we will be using, the list of materials created, the render settings, and many more things that we will discuss later.
Located right under the Shading panel, we see the Properties panel. This is a dynamic panel that will show us information about whatever we have selected in the items list or the shading tree.
If you have your camera selected, it will show information about the camera's properties. It will do the same if you have a material selected, a shader, and so on.
