Presets for both DAZ Default and Uber Surface shaders means that you can change the reflection maps on owned products without affecting other parts of the shader. Also included are Fantom Reflection Domes which surround the whole scene, providing usage of the maps on surfaces with raytraced reflections without affecting your backgrounds. Turn "Fantom" off to use these Reflection Domes as lower resolution backdrops similar to my HDR Pro-Sets!
