living Room

[dagor]

please don`t going to my satisfaction!!! i see alot of work wich more better than my. i never satisfied with my work )) and don`t be sad about it.

you have some fundamental mistake in your scene. just fix it and you`ll see it comes more better!!!

one of the mistake is flat ceiling. sun shine inside room and lit it. if you fix room your light will be from window and not from ceiling. don`t weld vertex as i did. just intersect wall with ceiling and wall with floor. but your geometry must have thickness.

second mistake is scale of your models. it`s not big mistake but sometimes it works wrong. if you scale up or scale down your model with scale tool you must apply resetXform from utilite toolbar. scaled model is the same size as before scale. i mean system size. not visible. and render use model in system size. so if you scale up your armchair in 5 time it`s still 5 time smaller for render. sometime is cause error. i`m talking about system and culture of scene creation and setup. i realy have not mistake in my scenes. it work perfectly every time. i only ajust render settings from scene to scene. sometime GI, sometime memory usage.

third mistake that you don`t use skymap in enviroment slot. i don`t see it there in your scene. it`s a system sun+sky+phiscamera. so using it togather is good!

fourth mistake that you use addinional light in the room in the begining of setup. why it`s wrong? there is disbalance in RC2 and in your scene. we think as a rule that sky+sun+phiscamera give us phisical correct result. don`t realy phisical correct but we will think so for a star point. you don`t know about light multiplier inside room. you set it on of your mind (of your sight) but you don`t know is it correct or not. you don`t have perfect artistic eye and don`t know is it good or know. by the way i don`t have artistic eye too. it`s hard to me make realy photoreal image but i learing every time. if you make mistake at this point you going to tweak everything (your light, your sun, your gamma and so on) and you don`t know what to tweak. so for you and me there is awesom tool. if we use this tool - we can think about 90% proof that image is correct! this tool is vraylight in phisical unit!!! i use lumenous unit for vraylight. so if you have good geometry and proper sky+sun+phisical camera set up, you can set up your inside lamp with phisical correct result. not realy phisical correct but we think it. because we need a system for work. for example you have room with 5 downlight in ceiling. you need day shot and night shot. as i said you just need good geometry, sky+sun+camera for day shot.

you turn on your downlight and set their reallife lumenous power for day shot. it`s work realy good in RC5. it compensate brightnes near window and make your image balanced with light. for the night shot you need just turn off sun+sky and ajust you camera for night as you doing photo in real life!!! you don`t need tweak your downlight for night. it still works perfectly.

 

and the last mistake you did is your material. you material need tweaking alot. and if you set up your light correctly but still have wrong material your result will be wrong in some areas. i said you use gray override because of this. you realy can feel light, you can feel atmosphere and don`t think about material and color.

i know it`s need some experience, but you are learning now and it`s ok for you. just continue practice in your free time. after 3-5 done project you starting to understand some thing. it`s realy only time and practice you need.

 

about my and your image in comparison. i don`t mean i make great result. it`s only quick set up to show you fundamentel principles.

 

your second gray image is staring be good. but you turned on inside room light. inside room was this wrong multiplier setup and your kill your daylight.

whiout inside room light it would be good daylight shot. if you set up proper your daylight you can say yourself - my sun and sky and camera is ok. so my daylight is ok. i like it. it looks like real. what to do in next step?

you can tweak inside lamp or you can tweak material. this is a step by step technique. you have one good result. you try to fix next part of your scene. don`t jump from one to another.

 

uhhh. i`ve wrote a lot of words. if you don`t understand something because of my english and our language barrier - just ask me. i try to make images for you.

 

anyway i don`t try to teach you. i just show you way i`ve done and my workflow. just try to help.

 

so i say it again. don`t be said becaus of i am. just look at your pictures and ask you. is it good? how you think? yes you make it better but is it good for now? if you think it`s not good enought just keep improve it. ask yourself and other whats wrong?

i never think my work good. i neve satisfied with it. but i know about clients and deadline. i try to do everyting i can for make my work better in time. i`ll try always )))

 

we have all life to improve our work )))

Ok, I catch what u meant, I review my mistakes, first I will focus now on adjusting my day light, second, set the inside light (luminance), and I will attach the results,

About the materials, I don't get what u meant, by tweaking them, but its ok, later we discuss that. Or , you like to give me an example.

Oh, don't give matter about what I said "be sad that my results still not good enough", you know girls , always want the fast perfect results, but I'm soooooo patient and I will try until it's be good.

Take care, thanks for your directions, they helped and keep helping me.

[mare96]

i m sorry for the interruption, but i think your chat here is the best lesson for all newbies (like me).

keep talking!!

2Mimi mohd

i`m surprised that you a girl )) nice to meet you )

you right about first and second.

we can discuss you material later but for example:

floor tiles material on the your last image from #22 post. there is no bump seams between tiles! your floor looks flat.

there is no fresnel or fallof reflection! your seams must not be reflected!!

and now my floor fron #24 with bump and reflection for tiles and no reflection for seams. may be it too glossy, but i don`t know sort of your tiles ))

 

your mine

 

about indoor light for lumenous. you can find info about color and lumenous power on the manufacturer webpage like http://philips.com/. for example fluorescent tube lamp from philips.com datasheet. you need Correlated colour (k) and Lumen output (lm). don`t know what exactly type of lamp you need. but it almos like one on other. so try this or find your own lamp.

 

PS. i don`t use watt in lamp unit because 2 different lamp with same light power in watt give different result.

it depent on performance index (efficiency) of lamp.

 

2mare96

you are welcome ))

we will contunue until we get good result or Mimi mohd stop improve it ))

If you are using the 2.2 gamma method, your color correction should be set to linear, exponential will give you the greyed out look. You dont need sRGB in the frame buffer either, because you have already set your gamma to 2.2 in your colour correction settings.

 

Oh.... and if you are using this method to brighten things up, it is also recommended you balance it out by darkening your materials using the vraycolor map in the diffuse slot (or adjusting your texture rgb value etc). Did you have a look at Lele's tutorials on gamma correction in the chaos group forums?

[dagor]

exponential color correction works fine. i use it here

i said about sRGB button in my previous post.

 

i don`t use vraycolor map. i ajust my material color on my sight. if it good in mateditor - it will be good in render. i should not ajust my texture rgb value because i set gamma 2.2 for input bitmap in max setings. i you speak about something - pleas give us a link or example to prove you words. pleas give me link to lele`s tutorial. actualy i don`t read any tutorial. there a alot of tutorial with very strange setting. i have no much time for read every tutorial. my gamma setting work fine. i never said it realy most right and good. i only share my setting, my workflow and my work.

2 dagor,

I didn't surprise that u was think that I'm a man, I get that when u said" you will be the last man talking about gamma with", but ….. nice to meet you too

And I'm working on adjustment, I think it will take some time, since I get busy with urgent work now, but I will continue, if God's well.

 

 

2 mare96

What you said wasn't interruption, I'm glad that someone beside me get benefit from Danial directions, this is the point from talking in public, you r welcome.

And surely, I will not stop until we get the best result, since we have here a good patient leader (Danial), and a hardworking GIRL, and that who will be me

Take care

 

2 flyte

Thanks for your notes, they will be considered, and I will appreciate the link for Lele's tutorials on gamma correction, and no harm from some examples.

Take care

[FlytE]

Dagor, politeness will get you far in life and so will google, but seeing as you seem to have neither I will post a link. Oh but, you dont read tutorials so this link is probably wasting your time.

Sweet, there are plenty of examples in that thread but here is the is a test I did to try it out:

Its alot to take in with those videos, but its worth it.... the .255 method renders faster, and will often look better

[dagor]

you are right at 110% about me ))

but if you have more constructive advice and critique with examples - post it here.

 

i asked you about link to check it. because may be there is some useful info that i have missed. you sarcasm is realy funny. it doesn`t bother me )) you are wellcome to discussian Andy Pennington.

[FlytE]

My sarcasm was probably uncalled for, but I have little time or patience for people who are ignorant and confrontational. My post was to help sweet, but at the time I was too busy to go searching for the post I was referring to. Thats as much of an explanation as I am willing to dignify this discussion with as I have no more interest in this pointless battle of words.

 

Sweet, good luck with your image.

[dagor]

yes, it`s usual words for boaster.

and you realy helped when said wrong unproved suggestion about exponential color mapping with gamma. if you find time for stupid me - you are still welcome ))

if you still want to chat in this manner - go PM ))

if you wanted or want to help try to find peace in yourself.

[Sweet Architect]

What's up guys:confused: , I just read the discussion between you , and allow me to say my opinion on that.

I think it doesn't matter who is right and who is wrong, because I believe no one is wrong here, every one has his own way to get a good result in render. May be the ways differ, but we all here have the same aim >>> (Help the new users of V-ray), and I'm one of those people, and surely I appreciate notes from anyone to get the best result.

Danial, offered his help from the beginning, i appreciate that sooooo much because he was patient with me, and I followed his way, and it works with me too, and definitely there are another ways.

 

FlytE, thanks for your notes, you are always welcome. I appreciate sharing your opinion.

[Sweet Architect]

Hello every one, sorry for the delay, as I said before there was an urgent work I had to do.

However, let’s we continue the discussion…….. if you are still available.

Last time, I said that I'll fix the daylight, ok, there is a Vraysun, skylight, Vray physical camera with parameters (f-no. =5.6, shutter speed 20 , film speed 150)

But the question here, shall I use the normal skylight, or the GI environment skylight, with the Vray sky on the slot.?? In the view attached I used both.

 

About the gamma settings, I tried many values, but I choose to use 1.4 value.

 

About the materials I tried to tweak them, for example, the floor tiles, I copied the map from the diffuse slot to the bump slot with value 80 , the same things I did to the wood material, in another words, any map I used for a material, I used the same map for the bump.

 

PS. I attached another view but the same settings above, because every time I render the view we used to work on, an error happened.

Another thing, don't look to the kitchen design, it has a simple arrangements because here I focused on the render issues.

[dream]

Hi, i think you can use one decoration light as your general light, with sphere shape or with some crystal with it (maybe), just try to break the formal living room.

Thanks... keep up the good work
