Making games for WebGL means our limitations are more than normal PC or Console games. We've chosen to optimize our assets using trim sheets and a custom vertex recolor shader to greatly reduce our texture footprint. Each building type shares a diffuse and normal map, hero props have the same, but 90% of our props all run on a single shared texture set and all our assets leverage vertex colors so we don't worry about color variation in the texture.
All buildings and half of these props as well as the custom shader were created by myself for our studio.
Home furniture props were made with the support of Vaikunth Raghavan.
