They are from BGF mod for BF2, the export is very easy, specially because they are just statics. Last time I used 3dsmax was 11 years ago for WaW, I remember nothing about it.
I went through most buildings in the meshviewer and I removed all the heavy ones and replaced them with light poly but yet very good looking buildings. This map will never get proper statics done, nobody will make them.
I used previously unused CMP stuff and added a couple of BGF statics (I will add more in the future). I put this stalingrad building because the previous one that was there lagged too much because it had no LODs. This one only has LOD0 and LOD1, it´s better than nothing.
That location is a placeholder, if that building doesn´t work I´ll see what I put there.
