Flipping wont change the fact the light comes from a precieved FRONT angle , only the angle. It will actually destroy the specular , reflection and precieved radiosity. I am showing a pic of the map facing normal. Please note the edges of the sphere. I'll post a flipped pic next and you will see that it ruins the lights effect to match the background. reflect spec , radiosity ect. I'm done hope some one see's the light LOL The rabbit
