A lightmap produces a new diffuse map with all the lighting information projected onto it. The workstation doing a kind of ‘pre-render’ to bake lighting highlights and shadows into a lightmap.The workstation calculating the light’s interaction with objects in the scene during the render, done in all production CPU rendering and most real time engines running on modern hardware.In 3D engines(both real time and otherwise) most lighting and shadow information in the final displayed image output is taken from the lights used in the scene. It is not typically used as its own map, and is instead usually combined with the diffuse map to bake in soft shadows. That means if you buy something we get a small commission at no extra cost to you( learn more)Īn Ambient Occlusion or AO map is a grayscale map which contains lighting data.
