Lit Sphere

[Guest Demfis Fyssicopulos]

Dear all,

What is the best way to create a sphere that renders as lit from the inside?

One way is to enable a Reflectivity>Glow shader to the sphere's texture. The Brightness can be set to more than 100%.

Another is to actually put a light inside the sphere and adjust the sphere texture transparency.

I think the Reflectivity>Backlit works, too. I think I recall Monadnoc using this?

Hi Benson,

Thank you!. The problem with the GLOW shader is that it looks flat. There is no intensity decay from the center outwards and it ends looking just like a dot. BACKLIT looks better but it gives the sphere an "Ecuador" outline for some reason.

When you use Backlit make sure that the texture also has its Cast Shadows turned off.

One easy trick, is to have a sphere with the color as a Texture - (Put a light inside - no shadows - if the sphere is glowing red - make this light red) - and another sphere over all ...

Each has different properties. Inside sphere Glow or Backlit Shader - The outside sphere could be clear and glossy. The Backlit shader may also need to be the matching color.

And to get that reflective look, make sure there is something in the scene to be reflected.
