here's the latest setup for those who want to use it... In this setup 1 blender unit equals 1 meter

So here is my house with the new and the old setting.

What do you think? Which is better?

The new one is better, since it's not as dark as the old one and you can see the whole thing more clearly.

the old one makes a more realistic impression.

The old one looks better.

can you show us a render without your texturing, the problem is you designed the textures and materials to fit with the old lighting, so you made it look right for that. whereas when you change to the new lighting it looks wrong. it is likely just a material settings issue.

things like specularity, and reflectivity have a HUGE impact on this.

The old one too dark, while the new one has too light shadows.

Thanks for trying it out. I already thought maybe to make the shadows a little darker, but your shadows seem almost too bright if you compare them to the test-cubes in this image:

Do you have a ground-plane surrounding the object in your scene (red on the screenshot in the attachment)? This is necessary for getting the right effect with Ambient Occlusion.

if you do have the ground plane you could try varying the light energy. In the table below, Sun energy is alway 1 (is 0,8 in the setting above) and AO is 3/2,5/2 from top to bottom. Maybe a little bit more contrast is better for darker buildings.

So i rendered my house now with the plane and without textures.

Without textures looks the new one much better. But with textur the old setting have more contrast and it looks more realistic, only the shadows on the front are too dark.

the new setting is indeed a whole lot better but as allltaken suggested your textures might have been adapted to the "old" setting and therefor might look better with the old setting

New Old
Old New...

On looking at it again, it seems to me that the difference is mainly the darker roof and paler walls on the new one. The floor actually looks better in the new. maybe you could try modifying wall colour and roof brightness? otherwise feel free also to play around with sun and AO energy.

tried a new building:

Hi there!

1st: I don't know how to use the new lightin-setups postet here. Is there anywhere a manual?
2nd: Whats about a uniform render setting? Render size, camera settings, camera position, ray settings, renderer (internal or extern (ie. YafRay)) I can't find them yet.

Thanks and greetz,
Alinator

To me, its not so much a brighter day - bright days have darker shadows. The shadows in New are softer which would imply some high level white clouds to diffuse the light. Personally I like New way better. Less harsh. However, for Tropic buildings, the harsher Old lighting may be more appropriate.

Alinator:

do you model with blender or another program? If you use blender, just start with the lighting setup. if you use another app start with the lighting scene, import your object, and then texture it. camera settings etc. are also in the lighting setup. For now, the size is 12,5x12,5m , later I will post settings for bigger tiles.

did you see the wiki page by the way? its http://wiki.openttd.org/index.php/GFXDev:Main_Page
