I am trying to achieve an effect as the attached image shows. The "glowing" lines in the middle.
How is this achieved? Especially the bright, white middle with light blue shine. Do I need Global Illumination for something like that? Trying to avoid GI because of the longer render times regarding animation.
I usually achieve that in post. A little glow on that object id. If you pay close attention, the reflection of that is not as bright as the lines itself. So I'm guessing that they changed something in post.
You'll need to get some light emission in your render for that overall look, so I'm guessing not using GI is not an option.
