Hi all,

 

I'm new here, signed up today! I'm an architecture student in the UK and I'm trying to *wow* my tutors with some realistic visuals of my idea (along with lots of sketches, hand models etc etc).

 

This is 3dsmax Design 2010 and Vray 2.0 (which was so cheap as a student!!)

 

 

Anyway, the scenes are of the apartments blocks inside from the project which is 8 apartments & 8 houses.

 

The problem I'm having is lighting the scene. I've spent 2 days rending over and over but it's either over exposed, or not light enough. Note that the ceiling part adjacent to the window is very bright and the rest of the ceiling is quite mottled. Yet, none of the walls/floor are. If you look, behind the TV it's a similar story.

 

What could it be?

 

The v-ray camera's are practically default settings bar Shutter 50 and ISO 200. The sun/environment are also at default. I've tried a gamma 2.2 setup but the images feel a bit washed out for my taste. Is it simply because my windows are too small? I'm using LC&IR to render on a medium setting.

 

Thanks

I don't see anything that's unusual about your scene, the windows are higher on the wall therefore they cast more light on the ceiling and the ceiling is white anyway so it's going to show more light than the darker floor. You can try to minimize this by changing the sun angle and by reducing the amount of GI the ceiling receives but I wouldn't because your whole ceiling will get darker. The hot spot behind the TV is caused by the direct sun light bouncing off the back of your highly reflective TV material, you can try the same trick of reducing the amount of GI that material generates. The only thing that jumps out at me is the amount of GI noise on your ceiling, turn up your GI settings to eliminate this.

To add to Devin's comments, what type of image sampler are you using? The second image does not show the crown molding very well. Could be due to the lack of samples, color thresh. too low, etc. Please post settings.

 

The people seem a bit large for the scene, especially the woman standing.

 

Lastly, the chrome material IMO needs more blurry reflections. They are a bit too sharp.

Thanks guys!

 

I agree re:chrome/people comment and will change them.

 

I've posted my settings for ease of explanation. Your right though, the crown molding looks very poor indeed.

Interesting settings. Are you using SolidRocks? I would start by turning on your AA. You may have to up the max subdivs of your Adapt. DMC to no more than 10 or so.

 

The GI looks strange too. Maybe reset your GI and start with the basic presets for IR. Maybe set to medium or high, and then change the HSph. subdivs. to say 30 and the Interp. samples to 25. Start there. Next, change your light cache to maybe 1800 to 2000 subdivisions. That should help your splotchiness on the ceiling. Again, you will have to play with the settings a bit to get things to render fast enough for the quality.

 

My solution is definetly not the only one.
