The wall texture is made of 7-8 layers. The clean wall has some grain to it. The upper mold is overlay,
same as the lower mold, except the lower mold is in more contact with water so it had to be more dirty and more grass-like. The last were graffiti, just overlay and hard light layers.
Welcome Sign Texture
Welcome sign was made in entirely in Photoshop, graffiti from the game as well as the damage, composited in a bunch of noise and overlays. There are identical signs like these that welcome you to the town, so I used them as reference. If you're wondering what the sign says here's the translation;
pozdrav ekipi iz krvavica - greetings to the team from krvavica (a block)
dobrodosli u grad Sibenik - welcome to the town of Sibenik

Lighting and Rendering
There are 2 Omni Lights in the scene and Vray skylight. 1 Omni is used to light the entire scene, the 2. is only used to brighten the exterior. For the GI map I used Irridiance map, and there were no secondary bounces. I used "medium settings" with some small adjustments. The scene was broken up in 6 layers since rendering was the biggest problem. I didn't mix any mapping etc. I went straight to RGB pass. I first rendered the Irridiance map with all objects in the scene, saved it, and later on used for rendering the passes. The I rendered reflection pass and the refraction pass. After everything was rendered I opened AfterEffects and started to compose and work on the image.
