Are you allowed to post your image so we can see it? How are you lighting your scene? Are you using the V-Ray Sun and its environment/sky light? Are you keeping the sun relatively low in the sky, or high and bright? Low is better. Is your sun favoring one side of the building more than the other? Are you using the V-Ray physical camera? Are the renderings from the other 3D computer something they sent for marketing use? If so, I don't see any reason you can't at least link to their website so we can see their work for comparison.

hi guys

i attached the files

i want to make my render like untitled-1 named render..otherwise ext4_01 and yeniext03 are my works..

 

The image 'untitled-1' has a slightly cooler hue than yours, otherwise yours is better work and I dont see an issue. I think you've maybe reached the point where composition and post-production are the next skills to work on rather than render settings.

Tell your boss that if he designed some attractive architecture then at least you'd stand a chance of making it look beautiful in the rendering. The you wont have to quit because you'll already be out of a job ;)

Agree with Tom on "composition and post-production".

 

"My lighting is good but he is looking for perfect one.."

Not bad but take ext4-01.jpg, on a bright day as you depict, there is no way that the 'ceiling' of the appartment's interior should be visible to the

camera. Because the light outside should be magnitudes larger than that of each interior appartment, the reflection of the sky on the glass panes

should be very bright (strong and clear reflection). You would only see the sky reflected, not see through glass. That alone would take the image

further ahead.

As a general guide I like to have my sun come in at 90 degrees to the camera rather than right behind it. This will add a balance of light and shade and help bring out the smaller details in the building facade.

 

Another thing that helps is to lighten the top 1/3 of the building and darken the bottom 1/5th, this helps ground the buildings and add's a bit of airiness (if that is a word???) to the tops.

 

Colour balance between light and shade also adds depth, ie cool lights with warm shadows or warm lights with cool shadows. Richer colours closer to the camera, fading and desaturating the further from the camera add to a since of scale.

 

I agree with the glass comment, bring some life into the glass as this adds in another level of detail.

psd manager isn't going to save you - learning a bit of photoshop and simple compositional techniques is

 

practice on some simpler images and copy work you like - that reference image you posted is pretty weak - i would only aim for that if you were blind.

 

maybe its time to get a job elsewhere - isn't MIR in Norway?

Michael - when I initially replied to you, I hadn't noticed you referred to one of my old portfolio renderings. Sorry about that. To give you some info about that particular scene...

 

All of the landscaping is 3D models from one of the Evermotion libraries, aside from the two foreground trees which are photographs inserted via Photoshop.

 

The buildings on the left and right - those are from another library I bought a LONG time ago - I can't even remember the name of the library, but it's filled with stuff like (obviously) buildings, street lights, benches, etc. - street clutter stuff. It's all in 3D. Always populate the horizon line with something - even if it's a forest...

 

The cars driving down there street - I enabled motion blur and animated the cars driving down the street and positioned them where I thought they looked good, then rendered that one frame for my still. I probably could have added several more animated vehicles.

 

The shadow on the concrete in the foreground - that was a duplicate of one of those trees which I filled with black, blurred, then distorted to make it look 'right' with the scene.

 

The dark streaks on the street under the cars - those were two horizontal lines I painted with a soft brush in Photoshop on their own layer, then I distorted it to give it the correct perspective to line up with the street - much easier to do this method than to try to paint them straight onto the street and get the vanishing lines to match. Although, as I look at it now, I see I could have tried a little harder... :)

 

The Audi on the right is a photograph I found on Google, then masked out and saved to my library - that was from before I had a Dosch library of 3D vehicles. I added a little white glow to the headlights.

 

The sky was a Photoshop gradient, using the alpha channel of the .tiff or .tga output from Max.

 

The corners have a slight vignette applied for a 'photographic' feel.

 

The concrete has a black gradient that comes up from the bottom of the image to darken the foreground - I reduced the opacity and played with the layer's blend mode to get an effect I was happy with.

 

There is a slight noise added to the image for a film grain feel.

 

The windows were rendered out of Max in a way that allowed me to select them as a mask (applied a self-illumination with no other lights or GI turned on so they rendered as a solid color I could select in Photoshop - much easier to do via V-Ray, but I've never actually played with that feature yet). I then applied a slight green tint to them per the client's request.

 

Anyway, point being - you can get the model to render that way straight out of Max if you really wanted it to. But, it's much easier (and usually more cost effective) to get it 95% there, then finish it up in Photoshop. This guy taught me that...

I'm sure you're seen the V-Ray help file, but here is a link to the V-Ray Sun page.

 

http://www.spot3d.com/vray/help/200R1/examples_vraysun_sky.htm

 

The image you attached has a lot of compression artifacts. It's hard to see what you're trying to point out. The shadows look like they are crisp in my opinion, but the jpeg compression is blurring everything in general. If you're after soft shadows, you need to use the V-Ray Sun and increase the Size Multiplier till you're happy with it.

Well all you need to do is read the Vray help and it tells you what every setting does. You've received lots of good advice here. Usually the main issue people have with Vraysun is exposure, but you dont have that problem. You're control of Vray sun seems fine. And yes, if its softness you want then just increase the size of the sun.

The images you are posting as your goal are frankly not very good. If your boss is schizophrenic it will drive you nuts trying to please him, if I were you I would leave your sun settings as they are and concentrate on post techniques.

I think Micheal Serta is having the same issue that Mazda Jalali was having here:http://forums.cgarchitect.com/38511-vray-soft-light-shadow-2.html

 

... , skylight/environment issue on indirect lit areas as for example, a tree shadow:

"...as you see,shadows is so soft.have a look tree's shadow.."
