First post

First time posting here. These are a few images from an AIA competition a friend did a year ago. Architecture is not mine. C&C welcome.

Night shots still noisy for some reason...

I think these look excellent. My only complaint is that maybe some of the edges look a little hard. Also it might benefit from adding some slight deformation to the windows (huge noise bump map) to make the reflections not so planar.

Still, though -- quite nice.

The grass looks perfect. Is that just a texture map, or is it displacement too.

I may as well ask -- would you share that texture or material? If not, no problem... understood.

nice!
the daylight version r very well balanced! the night version r too dark imo...maybe a slight blueredish skylight and a moonlight cast?
it looks a little to "empty" for my taste...maybe some furniture, people or opened windows...might just make the difference!

My only complaint is that maybe some of the edges look a little hard

second that

nevertheless gr8 post!

second that - excellent grass, would appreciate some info on it,

Nice work,
Tom

thanks for the comments. the grass is just a bitmap with displacement, i will try to post the materials/settings tonight.

I like the idea of the noise/bmp map for the glass and yes the edges are all too sharp.

the night shots were harder than i expected ... render times are almost 4 times longer than the day shots.

Nice Renderings! Sweet Grass! Care to share your shader settings??

[cbb]

thanks again for the comments ... here are the settings and grass texture.

here is the grass texture again.

You said that the night shots took longer then the day shots. I have a feeling that the reason for it is that you have a lot more lights in the scene, they are being seen through glass, each light is in an enclosed area and they are all separated by walls And you are using QMC instead of irradience mapping with Light cache. Also, if you want to get rid of the noise in those lighted areas, increase the area lights subdivisions to something like 16. Other then that, there really isn't anything you can do about it. The irradience mapping will help a lot though.

I love the day lighting! Materials are perfect except it looks like you have some mapping problems on some of the fascia boards. What kind of trees are those?

[cbb]

I agree ... there are some mapping problems. The trees are from turbosquid , i'll have to go back and look up the name.

The whole project was really an exercise in figuring out vray. These are all rendered with LWF and i had to tweak the gamma on a lot of the materials using the color correct plugin.

[dellis]

I love them. The tiling in the grass is a little visible. What i usually do is use a mix map...put the same texture in both slots with varying tile amounts. Then use a noise map for the mix. You can also change the numbers in the high and low settings to make the patchiness more pronounced.

Great work!

Very nice renderings ! About how long did they take to render ?

[davision]

Thanks for the grass texture.

By the way --- how did you do the daylight? It is really on the money.

Did you use Vray's physical sun/sky?

[cbb]

tried the lighting every way i could think of (hdri, domelight, spotlight etc.) and finally would up with a gradient ramp in the environment slot and a large vray light very far away.

LWF helped a great deal with the light/dark balance and then tweaking the gamma for each material got it a little closer.

the daylight scenes took abut 2.5 hours at 2400x1200 and the night shots were about 5 hours at 1200x600.
