View Full Version : Lighting from an green sun

09 September 2011, 08:27 PM
Hey, I tried to post this a week ago, but for some reason it didn't take :banghead:

I'm working a scene in space, where the only real light source is a Huge Green Sun. Obviously, if the only light source was just green everything would look horrible, so I was wondering if anyone could give me some advice, or point me towards a tutorial that would help.

Thanks in advance

Let me try to understand exactly what you're trying to achieve. You want to have a green sun but you don't want your scene to feel overwhelmingly green, is that correct? Also please clarify which software and renderer you're using.

sorry for my lack of clarity
yes, i'm trying to avoid a completely green scene.

if it's any help, the sun wont be in view, it will be behind the camera.

i'm using Blender, with the internal render engine, although i may switch to LuxRender if blender internal produces unsatisfactory results.

thank you for your help

Why does the sun need to be green if you never see it? What I mean is your scene's going to look pretty strange if you never establish that it's being lit by a green sun.

What exactly is in your scene? There's no reason it has to look horrible, but the choices you make depend a lot on what you're lighting.

Can you post an image of your scene (or even better some renders you've already done) so we can get a better idea of what you're trying to do?

The sun has to be green, because the scene is based on another artists idea people who recognise the characters will know why the lighting is green.
I can't show you the scene, because i'm still modleing everything, I was asking for advice so I would know what to do by the time I got to the lighting phase.

If it's going to be very hard to light it, I suppose I could scrap the green sun idea and light with a more conventional setup.

I thought it was possible that there was some generic lighting setup I could use, but I can see that's not going to be possible.

thanks anyway :)

The simplest thing to do would be to take a regular lighting setup like you would for any other shot and then just grade the whole thing green in compositing.

Agreed, grading it is your best bet. Magic Bullitt works wonders.

This is not the best reference but is the closest thing I could find to explain my approach.

Your direct light should be white/yellow and your indirect and shadows should be green.

Maybe just make it a greenish swirly clouded sky... with a glint of green where it is really bright...I think colors of things would still evolve to stand out as opposed to having a green tint throughout...

the sun is actually green in real life. are u trying to get the color of real sunlight???. if so the light rays are filtered so many times i thinks virtually impossible to pull it off.

use a magenta filter
