Documentation

This effect applies additive specular highlights at fragment level (instead of OpenGL's vertex-level lighting) by using a cube map and reflective texgen. A texture matrix is computed to rotate the cube map automatically; this makes the specular effect consistent with respect to view direction and light position. The user can choose which light should be used to compute the texture matrix. This effect requires the GL_ARB_texture_env_add extension and one of the cube map extensions (GL_EXT_texture_cube_map, GL_ARB_texture_cube_map or OpenGL v1.3).
