Rendering and Shaders

Converter Tool

NOTE: The Converter replaces the MAX script plugin for exporting units. The converter can accept FBX files from most 3D tools.

Valid map slots to be used are Diffuse, Specular Colour, Glossiness, and Bump (which is the normal map). The exporter should correctly handle baked materials. The maps are available in the game shaders in the following order in samplers [0-3].

Diffuse Normal Specular Gloss
