i found this old script where i began to do something to change from old to new
bump map butnot certain if this is working !

can someone help to complete this
at least we would ahve an example for this!


 
class matobjectbut1(bpy.types.Panel):
 
 
 bl_label = "Hello from Material context"
 bl_space_type = "PROPERTIES"
 bl_region_type = "WINDOW"
 bl_context = "material"
 
 bl_show_header=True 
 
 
 
 def draw(self, context):
  obj = context.object
  layout = self.layout
 
 
 
class Objbutton1(matobjectbut1):
 bl_label = "Bump Algo"
 Display = 0
 
 def draw_header(self, context):
  layout = self.layout
#  layout.label(text="oldnew", icon='ICON_PHYSICS')
#  layout.label(text="oldnew", icon='GHOST_ENABLE')
 
 
#  layout.label(text="oldnew", icon='TRIA_LEFT')
  layout.label(text="oldnew", icon='BLENDER')
 #  No icon  word anymore 
 
 def draw(self, context):
  layout = self.layout
  row = layout.row()
  split = row.split(percentage=0.5)
  colL = split.column()
  colR = split.column()
 
  if bpy.types.Objbutton1.Display == 0:
   colL.operator("oldnew", text="New")
  else:
   colR.operator("oldnew", text="OLd")
 
 
class Obj_op1(bpy.types.Operator):
 bl_label = "oldnew"
 bl_idname = "oldnew"
 bl_description = "Change Algo"
 
 def invoke(self, context, event):
  bpy.types.Objbutton1.Display = 1 - bpy.types.Objbutton1.Display
  Bumpchange(bpy.types.Objbutton1.Display)
  return('FINISHED',)
 
def Bumpchange(state):
 print('Change Algo')
 sc = bpy.context.scene
 
 ob = sc.objects['Mesh']
 materials = bpy.data.materials
 
 print("state = ",state)
 print ('in bumpchange function')
 
 if state == 1:
  for m in materials:
   textures = m.textures
   try:
    for t in textures:
     t.new_bump = True
     ob.location.x=5.0
     print ('change to true')
   except:
    continue
 else:
  for m in materials:
   textures = m.textures
   try:
    for t in textures:
     t.new_bump = false
     ob.location.x=0.0
     print ('change to false')
   except:
    continue
 
 
print('Algo has been toggle')
 
bpy.types.register(Obj_op1)
bpy.types.register(Objbutton1)

Thanks happy 2.5
