Unity3D: How to make a glowing gradient sphere?

target

So I need a glowing sphere with a halo of light, which casts light on a near objects. Also, as you see on the image, sphere must have a gradient.

I'm using 2 spheres and point of light at the moment. And I really don't like the results: bad results

  • There is no gradient at all
  • I need to use second Point Light to cast light to near objects

So... is there any ideas?

Solution

  • I think you have two needs,

    (1) the "actual" light which casts a light on nearby objects.

    (So, I mean that is literally a UnityEngine.Light http://docs.unity3d.com/ScriptReference/Light.html )

    (2) Separately, you need (basically) a "glowing orb" that looks like the white and yellow thing in your image.

    These two things are completely separate.

    You should indeed do them separately.

    Now regarding "2" how to make a glow, that's called a "bloom". There is a lot to look in to but this will probably do it for you:

    Note that getting a good glow is not that easy.

    Here's a really great asset, that's actually free for goodness sake,

    you should surely get that to experiment with at first. There are other well-known assets as well, like https://www.assetstore.unity3d.com/en/#!/content/8238

    Be sure to google for many QA on the glow topic.
