# Mapping image settings

Simplygon can generate one or more mapping images, which can be used to cast material data from the original geometry onto the reduced geometry after the processing has completed.

A Mapping image is basically a texture on the reduced geometry where each pixel contains information of which triangle and barycentric coordinate on the original geometry that the pixel corresponds to.

The settings contains basic things like the desired texture dimensions of the mapping image to create, and there is also a setting for whether new texcoords shall be generated and how these texcoords shall be generated on the processed mesh. Texcoords can either be created from scratch when using the Parameterizer, purely based on LOD geometry, or be created from the original texcoords when using the ChartAggregator.

Some settings has a prefix which means they are only relevant when the corresponding GeneratorType is used. Multiple mapping image generation currently only works with the Reduction processor.
