Lighting help wanted.

Post by JDA » Tue Apr 22, 2008 11:30 am

Hi!

I'm doing a tutorial and needs some
help with the lighting part of the tutorial.
Now you might say " why are you doing a tutorial
if you don't understand lighting in Indigo?"
Well you see I do to a point.
Ok so here's the deal...

Image 1 has 2 mesh emitters.

Notice how dark the top area of the image is.

Image 2 is covered with a cube with the bottom
removed. The 5 faces of the box emit light.
It gives nice uniform lighting but lacks highlights.

Now when I combine the 2 lighting methods
I don't get the uniform lighting.
The render always ends up like Image 1.

So my question is... How do I get the best of both worlds?

And before you say Violet I have tried that and I didn't get the results
I am looking for. So either I don't know what I am doing or Violet is not the answer.

Combine both and give more strenght to those two meshes, another suggestion would be using other tonemapping but reinhard.

Maybe, you could add a third filllight to compensate the darker area instead of illuminating the domino....

Or simply adjust the power of your lights so that the lights in 01 are stronger?

Or, make the meshlights in 01 smaller so that they are more like "point"/"spot" lights = stronger highlights.

(BTW, 02 could be simulated by simply using Background colour environment lighting - it's perfectly uniform)
