Ok, long time without an update, but that is because I was hard at work on the skybox.
The other function of the skybox is to add reflections to water. This is quite a challenge as the skybox is 1/16th scale, so in the case of custom close-up models such as the bridge I have to compile a 1/16th scale model and get it located precisely in the skybox. You may note some tree missing from the reflections, I am still debating decompiling and rescaling those so they can reflect, but I think that may be overkill anyways.
The image below is the start of the map. It is at the end of a long jut of land connected with a walking bridge.
The first half of the map will be a challenge to not get charged off into the river.
This image shows a constructions site along the walking trail. It also shows the railroad bridge which is located both in the skybox and in the game map. Way off in the distance is the Lamar street bridge.
