[Closed] class of different materials

Take a look at this…

http://davewortley.wordpress.com/2012/06/21/classes-superclassof-and-classof/

 here is a sample function that print material classes info:

     fn showMaterialClasses showProps:off asStream:off sorted:#none = 
     (
     	fn sortByClass c1 c2 = stricmp (c1 as string) (c2 as string)
     	fn sortByName c1 c2 = stricmp c1.localizedName c2.localizedName
     	fn sortByCategory c1 c2 extraSort:sortByClass = if (a = stricmp c1.category c2.category) != 0 then a else extraSort c1 c2
     		
     	classes = material.classes 
     	case sorted of
     	(
     		   #class: qsort classes sortByClass
     		    #name: qsort classes sortByName
     		#category: qsort classes sortByCategory
     	)
     	
     	ss = if asStream then stringstream "" else newscript()
     
     	for class in classes do 
     	(
     		format "Class: %
Category: %
ClassID: %
Name: %
Creatable: %
" (class as string) class.category class.classID class.localizedName class.creatable to:ss
     		if showProps and class.creatable do 
     		(
     			format "Properties:
" to:ss
     			showproperties (createinstance class) to:ss 
     		)
     		format "
" to:ss
     	)
     	
     	if asStream do
     	(
     		clearlistener()
     		format "%
" (ss as string)
     	)
     	classes.count
     )
     /*
     showMaterialClasses()
     showMaterialClasses sorted:#category
     showMaterialClasses showProps:on asStream:on sorted:#name
     */
     

Thanks for the replys, I think I’m getting somewhere, the phrase I was looking for was “Autodesk_Material” which covers all of the autodesk materials. The next problem I have is that the node connected into the materials which have the texturemaps attached to are “Autodesk Bitmap” nodes as opposed to normal “Bitmap” nodes and I am unable to find a way of queering which texture map is connected to the Autodesk map nodes.

The following works correctly if normal bitmap nodes are used

    for varMat in scenematerials do
    (
    if classof varMat == Autodesk_Material then
    (
    print varMat
    )
    if hasProperty varMat "Generic_Image" then
    (
    if classof varMat.Generic_Image == Bitmaptexture then
    (
    varGenericTextureName = filenameFromPath(varMat.Generic_Image.filename)
    print varGenericTextureName
    )
    )
    ) 
  

however with the autodek node it can't find the property .filename and I can't find the equilavant. This is what I have so far, it finds the autodesk bitmap node but can't find the name of the attached texture map

    for varMat in scenematerials do
    (
    if classof varMat == Autodesk_Material then
    (
    print varMat
    )
    if hasProperty varMat "Generic_Image" then
    (
    if classof varMat.Generic_Image == Autodesk_Map then
    (
    varGenericTextureName = filenameFromPath(varMat.Generic_Image.filename)
    print varGenericTextureName
    )
    )
    )
     

Have you tried selecting an object in your scene that has an Autodesk_Material with an Autodesk_Map and typing into the listener?

show $.material.Generic_Image

Thanks for that. It turns out the phrase to replace “.filename” should be “.Parameters_Source” making the code

        for varMat in scenematerials do
        (
        if classof varMat == Autodesk_Material then
        (
        print varMat
        )
        if hasProperty varMat "Generic_Image" then
        (
        if classof varMat.Generic_Image == Autodesk_Map then
        (
        varGenericTextureName = varMat.Generic_Image.Parameters_Source
        print varGenericTextureName
        )
        )
        )

I have taken out the "filenameFromPath" as that doesn't work with the Parameters_Source

Try inserting the line:

varGenericTextureName = varMat.Generic_Image.Parameters_Source
print (classOf varGenericTextureName)
print varGenericTextureName

It will tell you what class .Parameters_Source is.
