Hi Guys,

I designed this block so I can start learning and test light/materials using VIZ. I would appriciate C&C to help me out. I am using VIZ and faking radiosity.

 

The only materials added are the advert, aluminum, road and Tiles around window. I spent alot of time trying to get some good light but i couldnt get better than this

 

I tried rendering the same view with radiosity but I couldnt get the hang of the radiosity override materials. Can I use standard materials with radiosity?

You should primarily use standard materials. An advanced lighting override material is used when you want to specify your radiosity output beyond the capabilities of standard materials. By defalt 99% of the time standatd materials will be your source. You actually have a decent start with fakiosity. Go with it for a while. First off. This building would look much more interesting from eye level with the target at the same level as the camera, and give one side of the building more attention then the other. Don't focus directly to a corner if there's no reason for it. Lastly, since your sun is coming from the right, then the left side of the building should be darker. Your additional fakiosity lights are too bright. Try a few more like this, then give radiosity a try again. Global illuminttion will really improve the look of your scenes.

Thanks for your points Tim,

 

I am working on in it at the moment and shortly I should upload some updates. I changed my lights to radiosity and looks better. What I am worrying is that with tight scheduleas at work you cant really keep playing with radiosity.

 

My query is also regarding vegetation, ppl, trees etc... RPC dont work quite good with Radiosity. ANy ideas of what type I can use ??

 

Keep looking, soon uploading the new updates..........

This are some new shots with the updates, I am still not happy with some shades. The materials in the shade especially on the left hand side are looking strange and pixeled.

 

I am using radiosity, if you can give me some help to improve light I really appriciate. My settings are teh following:

 

Brightnes: 62.0

Contrast: 75

Midtones: 0.8

Physical Scale: 1500

Daylight and Exterior Selected

Looks better. Slightly better camera angle. You really need to go to your top view and place the camera and target where you want them. After you place them, select the line connecting the two, this will select both the camera and the target. Placing them from the top view automatically puts them at the same height at a height of 0. With both of them selected change to the front view and move them up 5.5 feet (not sure what mesuring system you us where you are but eye level is what I mean). This is really important. The view from where you are now is not flattering to the building at all.

 

RPC does woth with radiosity. Phisical scale in your environment settings may need to be adjusted to get the right look.

 

Time to study and experiment. If you want to figure this stuff out, it will have to be after hours if your too busy durring regular working hours. The settings you posted are only the environment settings, not your radiosity settings. In the radiosity settings I have found the best settings to adjust are the filtering (3-5 is usually good), use regather and play with rays oer sample and filter radious. Adaptive sampling helps too, you might test the initial sample spacing dimentions. Radisoity is great, but there is no one answer that will fix your problems. Make one adjustment at a time so you know what does what in a given scene.
