Impostor

Overview

An Impostor model can be created for a model if for instance it will be viewed from a distance and a certain direction. All the geometric details will be mapped as textures to the impostor plane. All material channels can be casted to it. Diffuse, ambient and specular textures etc. The normal map will contain information from both the original normal map and the geometry. An opacity channel will represent the holes of the original model.

Supported components

The Impostor processor works with:

• Material LOD

  • Mapping image
    Accessible from the mapping image settings.

  • Parameterizer
    Accessible from the mapping image settings.

  • Material caster
    Use it after the processing with the generated mapping image.
