These are for my favorite clients, deadline is Monday. The Low view is almost there, just a few model changes and a move to the left .The aerial view is changing to a day view.

 

C&C's welcome

Hi Jason,

 

I think both shots could do with more ambient light and a more discenrable direct light, maybe turn the area shadows down as well.

 

Overall the images need more contrast as well. The modelling and viewpoints look allright though.

[Justin Hunt]

Right about the Ambient, good call on the area shadows, I never seem to know if they should be hard or soft for twilight shots.

 

Just a side note, the name is Justin, not Jason. I'm not having a go its just something that many people have been getting wrong for most of my life. Sometimes I think I should change my name by Deed Pole:rolleyes:. It also made me look at my details , only to discover I spelt my own name wrong:( , fixed it now

[Nic H]

opppps! sorry about that, im perenially being spelt as nick instead of NIC as well.

 

What software do you use?

[Justin Hunt]

No worries

 

Max and the old work horse MR, no GI. I started with BrazilRS, looked good but took too long to render. Vray, even longer and not as good. MR was best compromise. Now that I have the weekend to render I might switch back to Brazil.

hey Justin,

I can't imagine that scene taking more than a few minutes to render, except if you're going to use Vray, it doesn't like transparecy maps, it prefers geometry, if those were 3d trees it would probably only take 4 minutes to render, I haven't used Brazil in a long time, but speed was never its best quality...

Hmmmm.... I think that would be a good challenge. Take a just huge monster file and have people use the same software and optimize for speed. I am sure people could forgive a bit of hardware discrepancies if we picked up speed tips.

Yes, using photo's of the materials so there will be no doubts about how they should look...good idea...

[Sawyer]

So how would that work? Give everyone base materials and let them adjust just certain parameters?

[manta]

yes, it doesn't matter how they get it to look like the material in the photo, it just has to look like it...like this for example...

[Justin Hunt]

I found out why it was taking so long, all the trees and plants are opacity maps, but in setting up the material I darkened the output in the diffuse slot, draged it into the opacity slot to use the alpha and forgot to reset the output. Therefore they were all 70% transparent ontop of the alpha. Once I fixed that I dropped major render time. The other was I was using the Metal Lume shader on all the alucobond material but set the samples to 40, once that was droped to 15 looked as good and much quicker. Also I had a bunch of area lights inside, those are now gone.

 

Brazil is slow but the skylight and image sampling are the best of the lot. Almost makes the rendertimes worth it, almost. To be honest I just set Vray and told it to render. @4000X2000px it took 7hours. It was a componded issue of transparent planting and bad settings. But a 11pm I think I could be forgiven;). I am now down to 3hours and with a little more tweeking I could be down to 1.

 

I usually do the landscape elements in PS, but I am trying a new methode, of doing it all in the render. The overhead of rendertime is supposed to offset the time it takes to colour correct the planting in PS. At the moment its not.

 

Here is an update, made a few changes to the glass facade.

[manta]

hey,

can we see all three renders and their render times...

[Justin Hunt]

Sad to say I didn't save the Vray one and the Brazil one is way outdated, but off the top of my head Vray was 6hours, Brazil 5hours, MR with Photons and FG 7 and MR with fakeocity 3hrs, (which is shown) .Bare in mind that these were done before I discovered my transparency issue.

 

Once I have put this one to bed I will do one of each.

 

Edit

Just looked at the image again, I feel that the road and cars are too dark. Is there anything else that is glaringly wrong or needs improving?

[Justin Hunt]

OK did some more work over the weekend,(I'll post tonight) managed to get the VRay one to work, rendered in 2:30. The opacity mapped trees worked fine. Only thing that bugs me is the lighting is very flat and not as dramatic as the MR version. I am going to try a different lighting setup to match the MR version. The glossies on the Alucobond material were completly washed out, almost invisible. I am not too worried about this as I am still getting to grips with VRay, but not enough to go full production just yet.

 

I also ran into some strange interface issues with VRay. At one stage whenever I transformed an object the viewport would automatically switch to a camera view. A restart fixed it though.

 

The Brazil scene kept on crashing, I think there is a rouge MR material. Didn't persue it too much though. I had enough irrits for one day by that stage:(

 

There is another round of design changes so once I have done those I shall post again

[Justin Hunt]

The twilight shot is almost there, bar design changes, but I am not happy with the aerial shot, good suggestions for doing elevated planting in Photshop are welcome. At this stage full 3D plants are not an option

 

These are both done with Vray. After spending the whole weekend tweeking the lighting and settings on the twilight shot I thought I may as well run with it. It took 4 hours to render and a lot of post work to bring it up to scratch

The aerial took 2 hours to render. Both @ 4000X2000px

JHV

[Justin Hunt]

Just a few design changes

[manta]

Hey Justin,

looking good, tell me are you taking advantage of vray's features i.e.

 

Using PPT for fast previews

 

Saving and reusing your GI maps

 

Using Vray proxy meshes for high poly objects like trees

[Justin Hunt]

The GI only takes 4 mins to calculate and the trees are curved planes. I could make full 3D bushes but these are working for me so no need really.

 

I aerial view is now rendering in 20 minutes as the planting is done in PS.

 

This one is starting to drag a little as my clients, client cant make up his mind with the entry.

 

JHV

[Justin Hunt]

These should be the final version, one never knows any more;)

 

Vray is really P###sing me off, quite a few times after a render, when I try to save the image Max exits out and I loose the render and any unsaved work AAAAGHHHH. I had to rerender a few times to get an image out.

 

C&C's welcome

Vray/Max crashes out sometines when you zoom in and out of the render in the max render viewport, or if you cancel renders half way through.

 

I've learnt, once i've hit the render button just to leave it alone until its finished, and always save before rendering.

 

I think the image has come along way compared to your first image, i like it. Its very hard to get a shed to look good, but you're pulled it off.

[Justin Hunt]

Thanks, the client is great in the fact they do great designs and are willing to let me run with the look and feel of the image.

 

Yea, it crashes after the render has been completed, the machine has been sitting there for a while doing nothing, I then try and save the image and max hangs and crashes. I suppose that it teaches me to save before rendering and render to file as well. I have a feeling it has something to do with my anti-virus software.
