Finally getting around to making my Pearl Harbor map so it will work in the new versions. XJazz helped me understand how to do a few things with objects using notepad and I was able to make more of the harbor.
Before I added other objects to the ground object, you were able to go through the transparent parts (where the water is)
Therefore a PT boat could safely go through the harbor. When I first built it as a square tile object, I did not select "Display Terrain Beneath Tile" and I was still able to shoot the water and have splashes come up. But the water was replaced with nothing so it looked like the sky there. I changed properties in OE and re-built it and now I cannot shoot the water, it acts like the object continues over the water now.
How can I get the ground object to act like it did before I built it in the OE so the water will act like water and not part of the object?
