I am wondering how to create a halo like effect using either Cycles or EVEE.
The Dragonball reference image is not quite what I want to achieve since I want to be have control over the distance of the halo from the object it is being emitted/coming from. Hope my sketch illustrates what I mean. Basically to have control over the distance of the inner border of the halo (lightblue).
In my naive mind I was thinking maybe a color ramp plugged somewhere with an Emission Shader would do the trick, but I don’t know enough about Nodes to build the shader …
Does anyone have an idea how something like this could be achieved?
