I m working on a project and I need some tips about exterior, scene setup (lighting, camera etc...)


One of my biggest concern is do i have to use radiosity,cause when i use it time of render increase in irrational way, thought i have very tight deadline.

My current setup is like this:

Light setup:1 area light (80%intensity), 2 Distant lights (20%and 13 intensity)
Render Globals:
Render:Ray trace shadow, ray trace reflection,
Filter: Antialiaze:classic enhanced medium, Reconstruction filter:classic,
Global illumination:none


What are the do and don't in exterior.


by the way Exception I like your work very much, you are my hero.

Hi Waly,

Thanks.

You want to use the perspective camera instead of the classic camera.
Also, you can use backdrop-only radiosity which is very fast, and should not add to your render time much. Make sure your sun area light is set to quality 2 or so, that will speed up your render.

With exteriors its important to balance the light and the backdrop image. I would suggest using the SunSky procedural by Dpont.

Thanks Exception, for the tips I'm sure that the tips you gave will improve my project and will fasten the render time.

Is this a still or an animation?
In either case, I forgot to say, use interpolated backdrop only. Or interpolated FG. That should also be fast.

Thanks again Exception, a few hours I've been playing with setting and i m just getting some pleased results thanks to your tips.

It's an animation. Is there anything else that i should add to improve the animation and fasten the render.

What version are you using?
If you can, wait for 9.5 to come out or get in on the beta.
There are more advantages going that route.

I m using Lightwave 9 but i can also use 9.3.1 if needed.

I have very tight deadline so I have' t got that luxury of time to wait for the 9.5 version to come out.

I think that i have some pleased results. Here is a rendered frame of the animation. Don t mind the blur it s because of motion blur.
Shortly i will send the animation.

I wan t to share my quad core PC experience that i had in this project.
I begun working with a single core PC, and tried to do some test render,on a one core PC for a single frame it took 2h 25min, than the same frame i rendered on a quad core PC, guess what it took only 9min 20sec it s a big difference so i realized that quad core PC is essential for the job that we are doing.


cheers.
