Quote - Just click on the image to see it larger and read the shader. The magic of bubbles is in their reflection. So, try the settings shown above. Just as important is the environment that is reflected in the bubbles. Having an object that is nearly transparent, yet reflective, makes it disappear sometimes. Mark

Thanks for the info; few questions: What is "Fake Fresnel?" I don't see in list of options. What step/s did you use to create the "Source 2 / Shader" combo under "Reflection?" I can see what you have in the "Source 2" part of the shader but, of course, no other values are visible at the level of your screen capture. What are numbers are you using that I can't see? Thanks, Jim
