We have decided to make levels that are some what British. So we started to make Tower bridge, not to be mistaken as London bridge. I mocked up a small block version of it to test how it would play on the game. Discovering that the camera needs to be on one side of the bridge so you can see the character. Placing the player spawn points on one side and a mass of zombie spawn points on the other made the level work as if the zombies were trying to get over the bridge for there next meal. The bridge was looking plain so I added some cars and road blocks even a few of the side fencing to get in the way. Surprisingly it resulted in the zombies doing crazy jumps towards the Animals. All the fast zombies run like mad men across the bridge.
To create a more finished design, I went to tower bridge with my camera and took pictures to use as textures. I must of looked like a really strange tourist taking closeups of bricks , floors and paint work…
Back at the studio I started to make a cleaner model with the reference and using the photos to texture the bridge. Some of the images needed to be flattened to match the look of the game. This involved taking a photo that was at a slight angle and getting rid of the perspective on window frames, door ways and arches. It took a long time to get right.
UV mapping cleverly I managed to keep the texture quite small . Most of the bridge is repeatable from the two big towers to the bridge banisters. So took this into consideration when laying out the textures. Creating Tiles that can be used across multiple places and details like windows that can be on both sides of the tower.
There is still work to do on the level but bridge is almost done. The thing with doing this level is that it’s not just the bridge. I’ll have to put detail into the water and also the background building. My plan is to create repeatable windows that can be used in tiles across multiple simple building shapes and also iconic ones like London’s town hall.
The water will need to use a shader with animation on it to make the waves look good. I took some photos of the Thames water and its defiantly not blue! So I’m going to attempt to use shader forge along with research about water shaders to create an awesome final shader.
