Delete Unused Nodes in 3dsmax

[galagast]

hmm.. one way i recall max handles its materials is through maxscripts' "scenematerials" function. This is where materials in the scene are stored, once you delete an object that has a material assigned, it is also deleted in the scenematerials.. although it doesnt update very much interactively...(i mean that you need to relaod the scene so that you'd get a fresh scenematerials)

If you were refering to materials in the Material Editor, you could run this script:
for i in 1 to 24 do for m in scenematerials where m.name != ((medit.GetTopMtlSlot i).name) do meditmaterials[i] = standard()This will loop through each material editor slot, get and compare base names from the material editor and the scene materials, if a mismatch is found, it will reset the current slot to a default one... although this wont usually work with scenes having same material names.. might as well backup your file first before running this script.:)

i might be making things more complicated, sori... hope this helps.
