Living Room Project - Help Req! :)

[dannytomlinson]

Hi Guys, i was coating along with decorating the missus parents living room and i figured id do a model to show them some layouts etc... However, i seem to have run into a problem - the render below cam out right (this one i took the 'roof' off) so its all light - the walls are white etc, all is good.



Then i progressed further with one with the ceiling in-situ and the colours are all wrong, theres noise on my wall material (simply increase subs?) and theres a lot of light burn from the sun... i guess its the colour issue that beefs me the most - i assume is the floor color reflecting onto the wall ceiling and its natural - but, i white washed this room with the same floor the other day and the walls didnt take on the colour - they where still brite white like the first image...




Anyway, if any of u guys can spare some of your vray iq it would be much appreciated!

Re: Living Room Project - Help Req!

Your approach it's not entirely correct. You should make a good use of those big windows you have. I think it's enough just to use the sun for lighting. I f you really want more light, put some rect. lights outside the windows, to simulate the skylight. Also, at the "color mapping" use"exponential" as type with dark multiplier 1 and bright multiplier 0.8. That should help you with keeping the walls white. Use physical camera, with shutter speed 30 f-number 11 and ISO 200. If it's too bright, make shutter speed like 50 or 80. At the color mapping, check the 3 things on the right side (affect background, clamp output and sub-pixel) to remove the eventual "hot spots" or very bright pixels . That should do.
Good luck!

Re: Living Room Project - Help Req!

Right, havent had chance to enact your suggestions up until now - looks much better - the walls are white - thoese setting really did the trick, thanks. Heres where i am with it now - i'm much happier with the project now - this image has had a little photoshop work - but it still doesnt seem the have the 'zing' or realism that i see elsewhere... here for example - it seems to have a real crispness that i cant seem to acheive http://www.9jcg.com/tutorials/neosca...enes_p1_04.jpg



Also, with displacement - if i set the edge length around 3 and subs around 750 i get reasonable render times - about 6 or so mins - as soon as i change the settings for something finer - like edge length ~1 or less (as seen on a tutorial on here) it goes into a 4 hour job - this with an i7 machine! Is there something im missing here? Would a post of my visop settings be useful?...also it seems i has a bit less noise on the first render - seemed much sharper too

Thanks again, D

Re: Living Room Project - Help Req!

Its still a great render Danny, much improved from the 2nd shot you posted.

Re: Living Room Project - Help Req!

yeah you really improved it, I like it... still a bit noisy though and the rug doesn't look "soft" but spikey. I don't know if this helps but maybe you could slice it in smaller faces and then adjust the displacement parameters? I thought I read somewhere on this forum it renders quicker becuse of the subdivs or something. (Not sure) but thought Jackson wrote it.

Hey Danny,
Looks much better. To make it less noisy set the noise threshold to 0.005. Also to get close to that image you can apply a sharper AA for instance Cutmull Rom.

Re: Living Room Project - Help Req!

Thanks again, will give that a go (displacement/AA/Noise) with a higher resolution as well perhaps... keep you guys updated!... sorry to be a burden but anyone else got tips on how to soften up that displacement up? Thanks

Re: Living Room Project - Help Req!

Just decrease Disp. multiplier. The higher the value the longer and thiner those "spikes" get.

Re: Living Room Project - Help Req!

Try for displacement edge length 2, and subs around 1000 multiplier 1, and for the multiplier of the displacement map 0.7. I get pretty decent displacement with those settings. Something like that (but I think that the map that you use, has something to do with the result)

Re: Living Room Project - Help Req!

Here you go guys, i took what you said on board - changed up the rug like you said... Crits again please if you can spare 5 secs!

...and another angle...

Re: Living Room Project - Help Req!

D, this is way better! Look at the lamp for example, it's not looking flat anymore! What exactly did you do? The scene looks very good, and the light it's obvious stronger. Anyway, you should be proud, that's a darn good looking rendering!
Congrats
