After some testings...

[Sputnik]

...my first Vray-C4D-Render!
Morning light in an industry-building in Berlin (the model was built for a current restauration project on this abandoned factory)...
..only sun/sky-light
Image scaled down from 1100px-height (MacBook Pro 2,16 GHz)
I know many things could be improved and GI settings not optimal but after these first steps... I have a feeling vray was a good decision! :)

very nice!
could you share your settings.. :oops:

Looks great love the quality of light and the composition

[rhodesy]

looking really good and an exciting project. I love the fade from dark to light on the roof - did you do anything special there in your mat/render settings? It works really well with the sky colour.

[Sputnik]

Thank you very much -I was indeed a little "surprised" abut the quality of light: It was always a hard struggle in AR.

@glass.use:
The settings: It´s just the preinstalled High-Quality-preset (in GI-window)
with small changes according to recomendations in some other threads:

Antialiasing: adapt. DMC 1/10
IRmap: -3/-2
Hemisph. subdiv:70
Interpol. samples: 30
Physical Camera with F-number 2,6 and shutter speed 380 focused (in C4D settings) on 1000 cm with DOF (so the longer rendertime :( but the DOF is barely noticeable because of the far focus point (it was very strong on focus 200cm))
The light is only sun/sky (with reduced blue (in camera-settings > white balance -hint from Stefan)

@rhodesy:
The fade is automaticaly generated by the physical sky: I suppose because the sun-position is very low (in the morning) so the lower part of the sky is brighter (?)
..the camera setting of course have to fit to this. For example: shutter speed or F-number lower: the whole sky would be bright.
I simply tested some different days and times of day to find an adequate lighting...

l..the fade from dark to light on the roof

Sorry, I thought about the sky :roll:
The reason for the fade on the underside of the roof is the result of the vignetting-effect (in camera settings).
Apparently the vertical warping in the upper part of the image caused by the strong camera-shifting also influences vignetting-effects warping them too in the same direction.

Sputnik you have inspired me to have a go myself with a model I did a few years ago, thanks for the tips. I am loving the simplicity of setting up scenes now I am begining to scratch the surface of what vray can do.

wow...

But this need more AA!

The lines of the windows in the backgrund are cutted

[marshalartist]

Yes more AA would be good but I wanted to keep the render time down. I am just experimenting. This took just over 8 minutes which I think is quite amazing.

[Sputnik]

cool...
this view would be surely interesting with a strong DOF and focus on the first sculpture.
By the way: Is this sculpture a free model? Where would I find it?:oops:

[marshalartist]

Thanks Sputnik I will try DOF when I get time. The statue is based on meg with all the detail taken out, PM me and i will send it to you.
