When a texture is mapped to geometry in Blender, under "Game Properties", you can select to map the texture to "UV Coordinates", or to "Reflection". Using "Reflection" moves the object's texture along the object's normals based on the rotation of the object/camera, making a texture appear to gleam and be metallic. I am trying to do this in OpenGL. Is there a simple glEnable to do this, or will I have to move the texture based on the object and camera rotation? Thanks!
