View Full Version : Lighting Problems

Hey guys,

Hopefully someone here knows how to tackle this one.

Lately i have been trying to push myself in the lighting/rendering department of maya. I noticed an image over at 3dtotal.com (link below)...and thought i'd try it out, however as you can imagine, my version was way off, the room was dull, the walls were grey...it was just terrible..

the scene i developed is modelled to the likeness of the original just not as detailed.

Spot light
200,000 photons
Exponent - 1.2

Global Illumination
Accuracy 500
Radius 8

Wall Shader
Color White
Diffuse 0.8

any help or suggestions would be much appreciated.

btw, im aware of the GI radius/accuracy not being banged up, i just wanted a quick render to show the problem im having.

you have big "windows", in that case i would use a mia_physical_sky/sun node with FG multibounce and it should look good.

btw thiken your walls you well get nicer results

Increase the radius, increase the photon intensity and active Final gather, it could be a good start

dont expect to mimic that in 3d. Id bet that those walls werent as white in the clean render, and its had a fair amount done in post.

Hi Demetrius.
First of all, that reference image is probably tonemapped, which is half way to getting that bright tone instead of the grey dark walls.
Besides that, as some already said, final gathering will help a lot. You can also increase the diffuse of your material to 1 and raise the photon intensity. Using some direct lighting will contribute to final gathering too.
However, remember that it will be hard to achieve that look without tonemapping. If you're using maya 8.5, a lens shader called mia_exposure_simple will get you started.

Good luck!
