(NOTE: The old item set has been removed due to a glitch with IX, where I accidentally put an incorrect item into the set and I couldn't get it removed from it. I apologize for the "shameless" reupload, I'm not trying to bump my items in front of the list.)
Here is a set of balloon items for the Lagoon environment. This set includes new models that have been optimized to reduce vertex count and file size.
I suggest using the LOD versions to reduce the map file size.
