DESCRIPTION

Inspired by Detroit, indie artist Hristo Petrov creates a decidedly Unreal level, solo, in three weeks. Using Ürban PAD's GIS data import and procedural buildings features, he recreates Detroit, with a twist, and imports the city in UDK. Hristo replicated some of Detroit's distinctive urban features using Google Maps and Ürban PAD's procedural building editor. Watch the slideshow for a step-by-step account of how he did it.

Step 1: Import GIS Data

Hristo started with GIS data from the city of Detroit, available at www.michigan.gov

Step 2: Create a city mockup

Identify Detroit features using Google Maps.

6 types of roads (1-6 lanes) 3 types of sectors, or city blocks

Measure common road and sidewalk sizes to get accurate data.

Create a default road and default sector with Ürban PAD Editors.

Step 3: Import SHP file into Ürban PAD

Use fGIS software to clip and import a shapefile.

Final size: 633 roads

Create a basic specification and simulation in City Designer.

Creating a simulation allows you to test your city layout on the imported shapefile.

Step 3: Import SHP file into Ürban PAD

Using Google Maps as a reference, assign roads (1-6 lanes) to their real-life equivalents. Assign sector types to their real-life equivalents.

Step 4: Create Basic Props

Identify basic props: Lamppost Traffic light Tree

Create props in 3ds Max. Export and convert props to Ürban PAD .egg format with Mesh Converter.

Step 5: Create Landmark Buildings

Create landmark buildings using Sector Editor.

Step 6: Test the City Layout

Place the landmark buildings. Test the city scale. Optimize props. Edit and refine in Ürban PAD.

Step 7: Export the Final City

Export the final city as one or several files in Collada format. Merge the Collada files in 3ds Max to make an entire city.

Step 8: Adjust the City Make scale adjustments in 3ds Max. Tweak parcels and sectors in Ürban PAD.

Step 9: Export Scene to Unreal Export map objects from 3ds

Max to Unreal. Create materials for city

objects in Unreal. Add objects and props to

map using t3d importer for 3ds Max.

Adjust lighting and settings in Unreal.
