Kitchen

[ALTO]

Hi all, here is my first work done with VfR4 beta1:







Some info:
GI: Irr+Lc
Final images resolution: 1700x1200 px
Rendering times: from 1,30h to 2,40h
Post: levels and glow


I know there are some GI errors but i've used "low" values to reduce render times.

Re: Kitchen

Well done, only the jpg artefacts are to much and destroy the small details.
I like overbright view out the window. Nice detail.

What kind of env light did you use? Physical sky? I wonder me, that the sun light is not brighter and the reflected sun light show no effect at the room.

GI: my experience is, that the GI dosn't need so much time. For example, if an image need 1 hour, than the IM need less than 10 minutes. I would try to save time not per IM. Most blurry reflections need much time and here it helps to use the LC shortcut.

Re: Kitchen

Thanks Micha,
No physical sky, the good old method: Direct+Vraylight, color mapping Exponential;
I guess i need more practice with this "physical instruments"... ;D

Yes you're right about GI (really i forgot to change values from preview renders to final renders)

Re: Kitchen

nice shots Alto, and indeed like Micha said, some loss due to jpg compression. The images are worth higher quality jpg's.

Re: Kitchen

Great images...Try working wit some DE/lower base IR settings and see if that might either speed things up or get you better quality in the same timeframe. Also if your going to us LC for Glossy rays (which is a good idea) try lowering the default sample size from .02 to something like .01 or .005 (assuming scene scale). That might help make things speedy as well. Again great images, and next time save as a targa or something that is worth of the quality of your images.

Re: Kitchen

Thanks and sorry for bad jpeg quality, i have high resolution tiff used for prints, maybe i'll resize them again for web. :

Thanks also for your suggestions dalomar, i will try them with next renders!

Re: Kitchen

Nice renderings, and overall design! is there anyway to know your basic system configuration. I think the rendering times on all the images posted in this newsgroup should be listed alongside with the system specs (cpu/memory). Reason I asked is because I am planning on building a new machine, and I am not looking to spend big $$ on the latest and fastest chip.

Re: Kitchen

Thanks farined ;D

My specs:
AMD Dual Opteron 265
2Gb RAM
Nvidia Quadro FX1400
WinXp Pro 64bit

I think a nice config at the moment is with Dualcore E6600, cheap cpu and very easy to overclock ...but i've heard in april there will be some good price cuts!

If you like, a special suggestion for lighting: my observation is, that rooms show a camera obscura effect. The ceiling is darker and other colored than the ground, because the ground get more light from the sky and the ceiling from the earth of the exterior enviroment. Here I wrote about it some months befor:

Funny effect or?

Your ceiling area of the kitchen is so bright like the ground and give me the feeling, the room is not closed.
I think, the best photoreal effect is possible with a physical sky. This should create a color gardient at the walls.

Re: Kitchen

Micha I don't see the ceiling on these images.... :-\

I agree with you it should be a little bit darker,near the ceiling.

May be you can help me,is there a setting where we can reduce the bleeding?

Thanks,

Renee

Re: Kitchen

Nice effect Micha!

@RVallieres: What i miss most in VfR is per-object GI, this helps a lot in lighting and of course to reduce color bleeding.
You could try to use GI control in Material editor.

Re: Kitchen

@RVallieres : only it's possible to increase the general indirect light bouncing per secondary GI engine multiplier ( I use 0.5 for exteriors and 0.8 for interiors). I have not tested it, but there is a saturation options at the GI options, this could help against to colorful bleeding. But I think, if the gamma values are right and the sec GI multiplier placed somewhere between 0.8...0.5, than anything should be fine.

Re: Kitchen

The last system a few years ago is showing its age when doing 3d modelling and rendering; all other applications run great. I have been thinking about the current dual core chips, and I may end up settling for one of those. Thanks again ALTO!

Re: Kitchen

very nice. i like your kitchen ;D

what kind of settings did you use for the satiny glass?thanks!
