Project metro was a MMO mobile game demo for Improbable Ltd. I made a whole environment of houses, props and landscape covering an area of about 500x500m. The plan was to create a pipeline and art solution for easily expandable city environment.
I decided to create a custom UV texturing system where with just one button click it was possible to colour selected polygons into any colour from 32x32px texture atlas. It was extremely efficient and performance friendly solution. It also fit the mobile game style very well.
