Bump Mapping

To use a bump map in a material, you can create a new material script inheriting from the base bump map script. Replace both texture image files with your own files.

import * from "BumpMap.material"
// Any number of lights, diffuse
material Cube_Lava_Normal : BumpMap_Base
{
    technique
    {
        pass ambient
        {
        }
        // Now do the lighting pass
        // NB we don't do decal texture here because this is repeated per light
        pass perlight
        {
            // Base bump map
            texture_unit normalmap
            {
                texture Cube_Lava_NORM.jpg
                colour_op replace
            }
        }

        // Decal pass
        pass decal
        {
            texture_unit decalmap
            {
                texture Cube_Lava_COLOR.jpg
            }
        }
    }
}

The base bump map material script is located at [media_directory]/materials/BumpMapping/BumpMap.material
