Hi, try this: Select 'sky and fog' in Bryce main menu click on the cloud icon ( the one with the rainbow ) activate 'moon phase' (is this the right name in english?) activate 'use moon image' shift the slider 'earth reflection' to the right ( 100%) activate sun/moon size and set the size to 70% select a clear athmosphere ( image on the right / upper triangle ) without clouds user the trackball 'sun/moon adjustment' to get the desired effect try to render the image To get the result you imagine, play around with the sliders Hope this will help you, have fun
