I use the image below as my "learning vehicle". I have now learned how to model balloons, texturing the balloons and put text on the balloons. One of the qualities of this image is the reflections (of a window ?). I have no idea how to do that. Is this a background image ? Some HDRi lighting ?
I used the answer of m.ardito to create this test file. I create four planes with the array modifier and made these planes emissive. I also created a sun lamp. This resulted in the image below. Although I now have the "window like" reflections" I still have a couple of issues left:
1) I think I need a second lamp (sun lamp) for lighting the sphere but this gives reflections I don't want. How to solve that 2) How to get those window like reflections with sharp edges ? My reflections have very soft edges
