Is it possible to create mayor menu ploppables which swim on game water? If yes, how can this be done?
Not possible. The closest thing you can do for flora is to raise the actual model with Model Tweaker. That model will only work at a specific depth though.
You may want Making Lots that Float on Water (http://sc4devotion.com/forums/index.php?topic=2443.0). The building part of a lot floats.
Thanks. I have already made floating Lots for my surfers. I just wanted to save some space in the menu and make it as MMP. I also tried to change the MMP type to building, but it only crashed the game, seems not possible. ()sad()
