image improvement

[q_vazk]

hey! welcome aboard..
i'm exactly in your situation right now, goin' about my first mental 'a la' vray renders...
first thing that comes into mind when looking at the image that the light outside is very bright compared to the room... it would be nice if someone more experienced could share some guidelines on light balancing.... anyhow, i think you should have posted this in 'vray like...' thread...
see you there

Well, here's a bit of prattle of mine which may or may not prove to be of aid to you.

First thing I felt when I saw your render was that ,"Whoa, this guy has got a glass covered floor".

I'm pretty sure that your intent was most likely to create a varnished parquet floor ya? You'd need a bump map with the grain of your wooden parquet blocks and perhaps use a material like mi_glossy_reflection to create the blurred reflections that would sell your floor as a varnished wood material.

2nd thing I noticed was that the Bed and the Curtain Top wood thing have a huuuuge grain for their wood texture. Unless that bed is made of a single slice of california redwood, I doubt that there'd be such a large wood grain pattern. Honestly, even if there are such beds with huge wood grain patterns, I don't really think they'd look great in your scene.

So try to work with a texture that has much smaller and finer grain patterns for your bed and curtain. You'd probably want to employ a little bit of that glossy reflection varnish type surface for the bed wood and maybe a less reflective version of the same for the curtain top thingie.

Hope this helps

Also, it looks strange to see the reflections of the curtains not have those square shadows like the curtains do. (Probably the ray depth limit is at 1 on the light, but the number of reflections is also limited in the render settings and on the shaders.) Also, the curtains don't seem to be getting fill light from the sky, it seems almost as if they are lit by a sunbeam but then total darkness from the other angles.

also the image seem to have bad gamma, set it in your framebuffer settings to 0.45 (1/2.2) or better, if you have maya 7, use francesca's lastest ctrl_buffers (http://forums.cgsociety.org/showthread.php?t=209991) shader to do tonemapping to the image. This is one of the most important things to get cool archviz pics :)

hi eliezer.garza, good on you for posting an image for feedback :)

first thing i would note, if you want feedback for photorealism you need to supply higher resolution images otherwise we can only really critique lighting, its hard to see the detail in shaders.

i would work on fine-tuning the lighting solution before getting too much in depth with shaders, otherwise you'll be making adjustments forever (i would make everything matte grey and go from there). as it is now the lighting is simply too dark. in real life, the room would be more lit up from a window of that size, there's also not enough disperssion of light around the room, by that i mean the white walls all appear too evenly lit, the light from outside is not really bouncing onto them. if those interior floor/wall mounted lights are on they're also not really having any effect, but having said that they might be those soft-glow halogen thingies which don't have much effect.... so not a big deal ;)

i personally don't like the window-light 'blow-out' effect 'cause it basically doesn't look real. but if you're going for an artistic shot the effect can look very nice, but keep in mind its not something you could give to an architecture client.

RE shader design in addition to what others have said, i think the curtains look too opaque and the 'flow' of the model with the big waves looks unrealistic, i would remodel them either more straight, or if wavy they wouldn't be so 'evenly wavy' if that makes sense.

the bed doesn't look like its part of the shot, the whites look too luminescant. under the bed its pitch black - that doesn't happen in real life unless the matress goes to the floor ;)

i hope something of that was useful - keep at it :)

Hi everyone,i appreciate that all of you have the time to post a reply .
I'll try to adjust the scene cosidering all your advices.
And when i consider that i have achieve a good result i'll post another image so ,if you have the time , can also take a look at it!

Thank's again!
