getting information about the object and its meshes through the 3D panel,

Importing 3D iles into
Photoshop.
When you import the 3D model into Photoshop from external sources, it is
imported with its mesh structure preserved. Furthermore, you can edit any of
the meshes separately through the Mesh section in the 3D panel.
Preserving the 3D model mesh depends on the format used to import the
3D object. Some formats, such as OBJ, convert all the 3D model meshes into
one compiled mesh. However, you cannot edit each of the models meshes
separately. In Figure 4.2, you can see the diference between one model
imported as an OBJ format and another in the 3DS format. Notice that the
structure of the OBJ ile consists of one mesh, but the 3DS imported ile
preserved the source model structure.
You can view the 3D model information and properties by selecting the 3D
layer and opening the 3D panel. If the 3D panel is not appearing in the
Photoshop workspace, you can display it by choosing 3D from the Window
top menu.
When the 3D panel opens, it displays the whole scene information (Figure
4.3). This information appears in a layered structure, with layers linked to
each other based on its related meshes. So each mesh appears as a main
layer and the textures applied to it appear under it in a sublayer.
Along with the meshes that appear in the scene structure, the light sources
and the camera that is applied to the 3D model appear in the structure as
main layers separate from the meshes.
