First post-first bad taste!

[stefanq]

Hello everyone! This scene took me two days, and the result it's far away from what I try to achieve... many issues, but what I really don't like, it's that "plastic" artificial look.. I use Irradiance Map and Light Cache , quite high presets,no map for environment and skylight, no physical camera. So..how far am I from "the perfect rendering" ? C&C are welcome :-[

Welcome.
I think with better lighting your render will look good.
At the moment the lighting is very flat (from behind the camera) resulting in a very flat look. Now if there was a window behind the camera (!), with daylight streaming in, casting soft shadows across the room it would all look quite different. Something like this-

Hi,

Actually, I found your render very realistic.
You get what a photograph would have using a flash in a dark room !
And it is not as plastic you seems to believe.
Just the books are too repetitive and dull.
The frame and the wallpaper are just perfect for me..

So the result is not as bad as you think, depending what you have in mind of, course...

As David tell you, the light from behind the camera always flatten the feeling..
You have two options
1/ use only several artificial lights
2/ try to get sunlight trough the windows, with cast shadows.

Your materials are fine, so let the light doing it...

Keep us posted

Tom

Re: First post-first bad taste!

Thanks guys for your advice! David... u are a very nice man ! Your replies are so important for us, "little" ones...you should be a teacher, really!! I just did what you told me, and now I wait the result ( I think I just "burned" a chair)... Tom, thanks for your time man!!! Those books.... I just didn't have the "nerves" to model them, so they are like u say they are. Your post push me to try to improve that scene right away!! Not all the materials are great, but the wallpaper...took me one hour. I try to put a "specular" map in the reflection, and I'm pretty happy with the result. But...very very expensive in rendering time! Have a bump map too in there, not quite visible. Thanks again guys for your time, and hope to become a little wizard just like you! I will post soon the result of your advice!

Re: First post-first bad taste!

hi stef, nice to see a post from you bro, about the books isue, you dont have to model them by your self, (unless you want to) you can get some good ones from the warehouse and then aply some good and diferent materials on them. i also think, that if you dont have a window you can also make a nice effect with a lighting, lamp, or something like that, other thing is that i can see a little noise on your render, when i have that problem and im using irradiance map and light cache is because of the camara settings, i recive some good advices in this forum that helps me a lot in this matter, but im a begginer just like you so this is just my humble opinion, excuse my english bro, im from mexico so not my first lenguaje...wait for your improves in the render.

Re: First post-first bad taste!

Hi teofas, thanks for your comments. The damn books...well, I do have a window, but I remove the capital "M" from the environment and background slots, because I stick with my stupid beginner presets, and I never used physical camera...shame on me...I did what David told me, and I really thought that I "flamed" some furniture over there, but in the end, it was a big washed room, with no texture, even my pattern from the wall disappeared..and it wasn't too bright...I just stop the render, but I don't give up!! O.. don't worry, your English is OK, and it's not my first language nether, I'm from Romania.

Re: First post-first bad taste!

Hi This is the result of physical camera, and daylight illumination. What is the best method to remove that noise from the reflections? I use shutter speed 125, F-number 11, ISO 400,adaptive subdivision, catmull rom, on irradiance map I have HSph 100, samples 40, light cache 140 subdivs...Thanks again for your support!

Re: First post-first bad taste!

hi stef, your ceiling and floor on second image i like them a lot, also the ceiling fan looks so real and the painting (from vermer righ?) and the frame are also very realistic, but why are the walls like that i mean they look like they have some kind of reflection with some kind of glossiness, i think that changing that the image will improve, about the noise i dont know why, lets wait some experts to answer.

Re: First post-first bad taste!

try this...render on primary engine QMC and secondary light cache.Then under image sampler,change to adaptive QMC and increase max subdivs to 200 or more.I'm sure u'll eliminate that mark on the wall.good rendering bro..

[stefanq]

Re: First post-first bad taste!

Thanks guys,I will not give up that rendering until everything it's gonna look OK! The fan, picture frame and the chair, it's from the warehouse, and that wallpaper have a very little amount of bump and a reflection map indeed. Very intuitive, teofas...That reflection map is good but now ,after I have just sun and sky, and no other light (direct light) to reflect... I just guess..I will follow mohd.akmali advice, and then, if it's not working, I will pot other lights in the scene. Only if I have the time..

I know it makes it more complicated to render, but I hope you agree that, once you have sorted out the highlights, it does make the light in the room more interesting - there is more light in the shadows and overall variation etc. Its nearly there.
Good Luck

Re: First post-first bad taste!

Yes David, you are so right! The room it's "alive" now, maybe it was not so simple scene for the beginning, but I try something more complex, with interesting materials also. And yes, it's hard, but that's the beauty of what we are doing, and definitely I'll push it forward! Thanks again for your very constructive opinion.

Re: First post-first bad taste!

OK...this is what I get with QMC and light cache, I get rid of noise, but I'm still not happy with the result. I'll stop now with this scene, and I will study more about lightning technique... so, what I learn from this experience, is that: good rendering = good lightning.

Re: First post-first bad taste!

Stef, bro!!! what a change!!! i know your making your best, and its having results, when i look the first one and then the last one, its so different, so happy for you, keep on the good work, im been honest...I know what you mean with time issue , i have to study and work, im merried and have some church responsabilities, so i have very long nigths studing (sacrifice sleeping for learning), render technichs and hope some day be good on it, so remember what i told you "2 newbies on the right direction" lets keep on working, hehe, se ya bro ;D

Re: First post-first bad taste!

TBH I generally avoid QMC like the plague as I much prefer the clarity of a IR+LC image. I'd imagine the easiest method of fixing this would be to have Sub-pixel mapping * clamp output selected from the colour mapping rollout.
