1. A system comprising:
one or more processors; and
a computer-readable storage medium coupled to the one or more processors, wherein the computer-readable storage medium comprises instructions that are configured to cause the one or more processors to perform operations comprising:
receive map data corresponding to a geographic region, wherein the map data includes a topography of the geographic region;
receive image data for at least a portion of the geographic region that includes one or more images of road paint;
generate a virtual environment corresponding to the geographic region, wherein the virtual environment is configured to simulate performance of an autonomous vehicle (AV) within the geographic region;
render, within the virtual environment, one or more road paint mesh objects simulating real-world road paint based on the one or more images of the road paint, wherein a shape of the one or more road paint mesh objects is based on the topography of the geographic region; and
simulate, within the virtual environment, AV sensor data based on the one or more road paint mesh objects.
