Desperately need help

[rozsadan]

Hi Everybody! I've just registered and I have to say I have a lot to learn. My goal now is to create a photorealistic room. So far I have not been able to figure out what is the essence of creating real-world like scenes. Here's my pic. It was made in VIZ 4 with Scanline Renderer using radiosity and lowering output leverls of materials in order to avoid the washed out effect. But still...it seems to be far from being photo realistic.

My question: is it possible to have photorealistic pics with the use of Scanline Renderer? Should I take my time and use Brazil? Or Insight? What else should I pay attention to?

 

Please help me, I do not know how to move on.

 

Thanks

 

Danny

Hi, and welcome.

I'd say that 99% of your efforts should go into materials.

for internal images, viz radiosity is pretty good, and it seems like you have a decent lighting in your pics. it still needs some refining, but thats not what holds from the pic to look photorealistic. Work on Materials.

Good luck.

Thanks bigcahunak for the reply. I cannot progress in creating more advanced materials as i do not know what to do. Can you recommend any site which contains materials for VIZ4 in mat format that I can learn from? Or can you send me some examples of excellent materials? Thx in advance. danny

About materials:

look back afew topics:

private house visualization:

I have gone through the same process

the trick about the materials is to desaturate them and to lower the values,

 

also if you have internal lights you can lower the sunlight strengh so there is less contrast with the inside.

Hi Danny,

We r (almost)close friends I've just sent u my interior scene with materials. Look at it and may u find it useful.

P.S.

I hope your mailbox can handle 3,73Mb file... It was compressed with zip and contains selfextracting exe files with photometrics, bitmaps, model, etc.

Hi Danny,

Did u find my files useful? Any questions?

hi roz

 

to oppose big c's answer my opinion of creating photorealism is 99% lighting. crack that and you can make even a poorly textured model sing! imagine you have a plain rendered white or grey square room in real life, no texturing, you then take a photo of it. you know the photo's real right? why? lighting. the chaos of gi and radiosity. thats my opinion anyway.

 

you can get super realistic renderings from a scanliner. look at programs like C4D. bucket rendering is just another rendering/processing method. programs like brazil just happen to utilise it. viz4, FR, c4d etc, can be used to make totally convincing piccys.

 

it's how you learn how to use them. brazil can also be used to make crappy pictures.

Its definitely not opposing what I said. I agree that lighting is probably the most important aspect. The only thing I ment is that in the image rozsadan provided lighting situation is much better than the materials.

Again, lighting is far from perfect, but if Danny would work on materials he'll get a much more photorealistic pic out of the current scene than if he'd work on lighting in this specific situation.

Hi all,

Lets say: lightning is 70% and materials are the rest... IMHO. The lights build atmosphere and emotions, but materials are the "filling key".One cann't exist without the another (lights and materials, I mean). So u both, STRAT and bigcahunak, r right. But, if I have to sacrifice lights or materials I would choose materials definitely.
