Hi !

I was asked to render a hotel room project for Marrakech.
This is my first Arch-viz job, since I usually render only my own tensile structure designs, and I'm not so comfortable with interior shots.
Don't be afraid to throw your tomatoes...

Give me an image to throw a tomato at ....

[osuire]

Thanks Ivox.

Apart from the noise, is there any obvious enhancement I could do ?

[Fernando Tella]

Yep, the obvious one: show the images.

[osuire]

I just made an ass of myself : I thought he meant the images didn't deserve tomatoes.
In fact, it seems I'm the only one to see the images.
I bet it's got something to do with Picasa web and access rights to the files.
I'm trying pict.com ; I hope you can see them now...

[JTB]

A very godd start, but you have to let them become clear if you want detailed comments...

[ivox3]

Don't worry about that comment --- nobody perfect in here.

I think your lighting could use adjustment. I'm not sure what it exactly is, but they seem to have an unrealistic quality.

Maybe you could tell us a bit about what kind of emitters/geometry you've used ?

[osuire]

Hi Ivox,

Light coming from outside is 100% physical sky.
Inside, I have a bunch of different emitters.
-Spherical hanging ligths have lightbulb shaped emitters which I tried to make as low poly as possible

-Peripheric wall lighting is a mesh with strips

-Halogen Spots Which have a parabolic reflector and a tiny emitter facing upwards


Here is the result with daylight only :



Night time with all artificial lighting on :



Same without spots and peripheral neons (only LED strips under the bed) :

[ivox3]

Although it achieves a nice effect, that reversed emitter would be adding to your noise .... Other than that, the emitters look fine, .. now I'm thinking that your red material might be impossibly red and that is oversaturating things.

But the more recent renders are better -- red material.

[osuire]

Actually, the render is the same ; I just used multilight.
I got the red color by converting a RAL tone that was imposed to me, but I might have gotten it wrong.
My color picker (in Xarax) gives me a RGB value in percentage, so I converted to the "0-255" scale by multiplying the percentages by 2.55
If anyone is willing to share a chart with the RGB values of RAL and PANTONE, I'd be real happy !

Is there any way of achieving a nice spotlight which will produce less noise ?
Or maybe I should just wait for V2

Apple was selling a colour bridge some time ago that has a Pantone/sRGB/HTML (and CMYK for daylight under 5000K as well) colour translation.
So feel free to throw a colour at me (e.g. Pantone 285C I'd give you an RGB value of 0/115/207, html 0073CF, CMYK 90/48/0/0).

Best done via pm if you want to get my attention...

greetings,

Hi osuire. Nice start. I like the sunlight version, emitter ones could be tweaked a bit to get a better effect
I have the complete RAL library if you like. All the colors are converted from RAL to RGB
http://www.maxwellrender.com/forum/view ... &hilit=ral

Someone built some Pantone charts too. Search a bit the mxm gallery

Not for RAL-RGB conversion, but anyway, I love this page to select colors: http://kuler.adobe.com/#themes/rating?time=30

Thanks Jomaga, Macray.
I'm really starting to love this forum...

[rusteberg]

looks like the images could use some variance in light temperature (which i think jomaga is implying)..... it all looks a bit uniform at the moment, meaning all your emitters seem to be emitting the same amount of light, in the same color/temperature..... lanterns especially should be much softer/warmer. unless you like the look of those nasty "go green" compact fluorescent bulbs that the U.S. government is trying to cram down our throats! they may be better for the environment (and so are cows that don't fart, according to some of our finest elected congressman), but i like the thought of my living room feeling like a living room instead of feeling like a sterile morgue environment... (sorry for the tangent rant )

Thanks for the advice !
My lightbulbs could definitely diffuse a warmer light.
The lights under the bed and peripheral neon lamps will definitely cast a cold light, but that's the architect's will...
I wonder what color temperature those ceiling spots have...
What are the property I should look for in the fabricator specs, and how do they relate to the values in Maxwell ?
