A good guide for the positioning of lighting for moods can be found here : http://www.videomaker.com/article/10216/
Some basic color theory : http://www.infoplease.com/spot/colors1.html

For an indoor scene your best place to start would be to create a spot light, give it the color you've decided on and have this light be your light with the highest intensity. When you have that key light exactly where you want it you can use spotlights,arealights and/or volumelights to create the light bouncing around the room. Happy lighting!


thanks very much

I'll do it now

Hi guys,

Here's my new render still no FG/GI.

C&C are more than welcome as always.

thanks.

This is my first post in a lighting challange. I thought i try a different aproach to scifi... a more industrial one. It's still WIP. Comments are welcome.



Rendered with Mental Ray in Maya: Rendertime: ~ 15min (with occl & depth pass)

ok I'm in.

here's my start. I'm going for a pretty dirty, dusty, sort of firefly-look.
Haven't worked on the shaders yet but I think I've set the mood I had pictured.
I think this darker set will really come alive once all the buttons are glowing.

So glad for the new scene! I've been a longtime lurker of these challenges, and I'm going to attempt to make this my first one.

Jeremy, thanks so much for continually holding these! A true inspiration for us all. Juan too! Thank you!

Thumbs up Feedback !

Kellios - Welcome!

philip - Good start. Some rim light outlining the robot, and/or maybe glowing eyes, could really help him pop.

kerschyb - That's great. There's a problem we call "tangency" (when two things line-up too well by accident) that's hurting the image. The white scanner-beam thing coming out of the robot lines-up too perfectly with the side wall of the hallway he's in. If you eliminate the tangency, the whole image will read better. I wonder if we couldn't be closer to the center of interest, too, if big parts of the bottom and right of the scene don't have much interesting?

ShamKiR - Nice work! I especially like the more close-up one. The subtle color in the eyes works. The bold purple in the buttons could be OK if you add more color to other parts of the shot, maybe add colored lights to the panels, but otherwise having just one part of the image so saturated, right near the bottom, makes them pop out too much.

Slazzo - That's great! Lots of fun! A little kick of light from the side might help the white of the robot pop-out better against the white background, and also could help give some presence to his black parts. Some more variety in the control panels would add to the shot, especially since it's such a wide shot that emphasizes the environment.

phil-w8 - Welcome! That's a good start! You don't need to crop off his hand. The reflections on the floor don't match the hallway they are reflecting: they don't show the bright lights, but they do show a reflection of a bright ceiling. Maybe this is a compositing mistake, but if it's all in one pass make sure your shadows are appearing in reflections, and make sure all the geometry is visible in reflections. A little more color variety in the lights ould help the scene.

Aleg8r - Nice scene! I think the robot needs more variety in his lighting, maybe light from above and the sides? Keep going!

wasimattar - Great! Nice carpaint shader on the bot. Keep going. Focus on his eyes, too!

runejw - Nice airy scene. Hopefully new files will help with providing a robot for the first scene. I'm glad you've got spares, though!

klabund - OK, if that's what you're going for, go for it. Shading that subtle is possible. Such a blank environment certainly focuses you on the colorful figure in the shot.


MircoP - Nice scene! I think the shadow on the floor in the center foreground becomes very dominant, make sure it fits with the overall lighting and comes from a realistic perspective.

2nd Version

Thanks for the great feedback Jeremy! I incorporated all of your suggestions, and did a lot of small tweaks to shadows, and added bounce lights. Mostly I brought the render time down from over an hour, to under 4 minutes. So I'm happy about that, but still a lot to do.

For a more constructive comment, you may want to try to color shift the robot fill light more toward green or maybe introduce some other blue sources in the scene, maybe some small lights?

Thank you!
I'm using RFM for this scene.
With the blue light, i tried to simulate an external light, such as the night light that comes through some aperture. It's not motivated. Yes, i'll shft my key_light toword the green in the next update.
Bye,
Mirco

Thank you Jeremy!
I'll change my key light toward a green and place it in a different perspective!
Bye,
Mirco
