With Firefly you can disconnect the sky map from the Skydome's Diffuse and Specular channels and plug it straight into the Ambient Colour channel. Set the ambient value to 1.0 and Diffuse and Specular to black. This will give you a self illuminating sky. Any lights that are used to light the skydome can also be deleted. Bill
