Photorealistic Render Setup?


#1

Hello
I have never got graphics looking Real there always like easyly scene as graphics i have tricked a few people with Highly Textured and Shadered well lighted scenes and used Vray or Brazil r/s but i havent achevied the Real Affect.

Yes i understand to make a Real scene you need Proper Light Rigging or maybe HDRI and you need Excellent Shaders to put character into the Object and give it a personal ID.
Of course you need Proper Textures that would actully be on the object in real life and used proply.
I can setup my Brazil r/s Very near to Photorealistic but as i am Running a Single-processor not even cg ready computer with 1GB ram 2-3 GHz i am limited to rendering movies and i dont have 5 years to render 1 scene of Animation.
By that time i think Computer Graphics would have Matured to Real by all Renders by means and my Scene would be simply crap.
So i decided to take on “Vray”
My Render has always been setup though Very Basic Usually simple , Normaly Adaptive Subdivision Analising and sometimes Indirect Illumination.
I have never actully thought about render setup and gone through and Experimented.
So why have i told you this , well i was wondering those who have made Very Realistic
Stills or even animations.
Im prepared for you to tell me it takes up to 5 days to render if so maybe i need to invest in a render node or a Dual Xeon but i just need a better understanding and also prehaps if someone has a .max file with a Realistic render setup for any of the following renders for 3ds max - Brazil r/s | Vray : most likly wanted | Final Render | Mental Ray |
It would be really helpful.
also what is some essential things to think about when making a Photorealistic still or animation.
Please help me out as i can help yous out with other things.
Thankyou for reading this and i hope you can help me out here.
And also help everyone else have a better understanding.

Thanx cya

In my opinion, there is no such thing as a photorealistic “render setup”.

Photorealism depends on all the factors of the scene (great modeling, great shading, great textures, great lighting), as you have even said.

If you believe that there exists some photorealistic recipe, then you’re mistaken. Getting a more powerful computer won’t help you either. Jurassic Park had some great looking dinosaurs, and yet it was rendered well over a decade ago on machines that don’t come close to a dual Xeon. More powerful computers just help you to create and handle more complex models and much larger textures (which don’t necessarily mean photorealism), plus they help to increase render power in terms of speed. In other words, a more powerful computer isn’t going to magically turn all of your work photorealistic.

That said though, I do believe that it is lighting that will make or break photorealism more than any other facet of the process. With clever lighting and shading (which are obviously instrinsically linked) you can make even a sphere look photorealistic. As I said, each factor is extremely important in the process, but lighting is that final crucial step - you can have the greatest model in the world, but a poor lighting setup will totally ruin it.

Yes i Agree with all that you said.

Yes i Agree with all that you said.
And i never wanted like Dual Xeon to make more better realistic graphics just to speeden up my Working so i can get my render done quick.
About jurrasic park you have made me think there you are right.
Even from a Light Specialist in Indonesia he told me lighting is the most important thing which i agreed apon with him and also now with you,
I have just look at fourms people talking about Tweaking Render settings like AA and Indirect illumination is what i really wanted more of a idea on.
But yes thanks for the reply as i have a better under standing of how it is lighting as i have herd it from 2 people now. :slight_smile:
if anyone has anything to say or to help out some more feel free.

Can I suggest posting on the lighting and rendering forum? You’ll probably get more focussed feedback there. There’s been quite a few threads where step by step iterations of render set-ups have been discussed and disected.

All the best,

Hi there,

I think I know what you mean when you say photorealistic, and I think there is a factor that if you can make your engine create, then you got the effect. It’s called radiosity.
Radiosity generates the reflection from all participants in the scence into a more realistic color. Have you ever drawn near a bright wall with your colorful shirt when you had some sun light on it ? You must have noticed the color relected from the wall was your shirts !

You need to look up the way to do it in your application though.
Good luck dude,

Making a pic photoreal also means breaking up/randomizing everything that’s too mathematically correct or “CG clean”. It’s already common knowledge to do this for stuff like textures, speculars, edges, arrays of objects, etc but it also applies to stuff that people don’t always consider…glows, distance fog, volumelights, light intensities, shadow falloffs, etc.
Much of this can be grunged up in post

Which brings in another important point; don’t always try to make a pic perfect in-render. Doing colourcorrections/grading, adding slight blurs, filmgrain, levels and stuff like that in post will save you heaps of time and give it that extra polish.
