Hello Don't know how you're going about getting it in to .ive, but doing artwork in 3dsMax and exporting using osgexp I can give some information you might find useful. In the exporter plugin for 3dsMax you must check a box called 'share duplicate states'. This cause duplicate materials to simply reference another objects material state (also can be other states). In and exported .osg file with this box checked (can't open .ive to check) In two objects using the same material the first object holds the material's properties, with the material having a unique ID say Material> Unique ID = 4> state properties. The second object when you get to its Material State will simply read Material> use unique ID 4, and that's all. You could also have to of the same objects were the geometry can be given a unique ID which can be referenced by the second. Have found as you say .ive files getting huge when embedding textures if this box is unchecked. Checking an .osg file with box unchecked file each object gets a full set of material properties including its textures. Guess would be that in the .ive your putting out as the exporter comes to a material listed, if not having the 'use unique id' it will simply embed any material listed even if used previously. So if you have a forest of 5000 trees all using the same texture, that texture will be embedded 5000 times. Hope that is of some use.
