Why did you build the 3ds Max versions with one massive master multi-subobject driving all the assets? This is eating so much un-nessisary memory when using just a single asset. For instance, VendingMachineC out of the CyberDistrict kit is taking up 6GB of RAM and is taking forever to merge into a file because of this. I'm better off just nuking all the textures and then re-texturing the asset when I need it. Which kind of defeats the purpose of some of these kits.
Please offer each asset in its own individual file with the material shader optimized. For a $200 pack, this is needed.
