#   This example illustrates how to get a material library and how to 

#   enumerate all materials in a library

#

from win32com.client import constants as c

app = Application

app.NewScene( "", 0 )

# First create some libraries and materials

sph = app.ActiveSceneRoot.AddGeometry( "Sphere", "MeshSurface" )

app.ApplyShader( "", sph, "", "", c.siLetLocalMaterialsOverlap )

rtn = app.CreateLibrary( "", 1 )

lib = rtn(0)

#app.Selection.Add( lib )

lib.Name = "MyLibrary"

app.SetCurrentMaterialLibrary( lib )

# Now enumerate all materials in all libraries

scn = app.ActiveProject.ActiveScene

matlibs = scn.MaterialLibraries

app.LogMessage( "There are " + str(matlibs.Count) + " libraries under the scene." )

for currlib in matlibs :

	app.LogMessage( currlib.Name + " has " + str(matlibs.Count) + " defined materials." )

	for currmat in currlib.Items :

		app.LogMessage( "  - " + currmat.Name )

# Expected result:

#INFO : There are 2 libraries under the scene.

#INFO : DefaultLib has 2 defined materials.

#INFO :   - Scene_Material

#INFO :   - Material

#INFO : MyLibrary has 2 defined materials.
