Tridem's WIP with SU and Kerkythea
-
thanks guys for precious comments
@Steelers: I know the sharpness is very bad but a such image takes 10 hours to cook, I'm trying to improve it before spending much more time to render.
@Roger: totally agree about the left light, thanks for letting me notice it. Since the sea is a background picture it doesn't produce reflections, I should add them in postpro like the reflection of the girl on the ground... but I'm not so sure those reflections could be so visible into the room...I'll think it over
-
how come you are using MLT preset? what's the advantage?
like the last image, nice mood. entourage well integrated too.

as I know, there are no really alternatives for a interior nightime shot. apart MLT gives the best result in terms of realism, biased methods need very high settings to resolve the complexity of lights and reflections. perhaps wait anyhow 10 hours or more, and finally find the picture full of white dots...
no thanks -
Angle of incidence equals the angle of reflection. The sun is low in the sky so light will reflect off the ocean from way out. When you can see that bright pool of light on the ocean, it means , you the viewer, are in line with the sun's reflection. This is why sailors and pirates used to wear eye patches. They were going blind taking sun sights. My daughter has a pool outside a west facing window and it send sun sparkes dancing all over the living room ceiling. Because the pool is small and close to the house this happens much earlier in the day. If the pool were stretched to the horizon you would see it closer to sunset.

no thanksMLT being unbiased is physically accurate but better tweaks on lightings are necessary esp for night shots. Probably can halves the noise and the rendering hrs.
Biased presets, ie Photon Map..would looks somewhat different compared, but decent rendering time is possible. But tweaking the presets is a tough call for most users IMHO.
Also couple of color or curves adjusments PP are needed to make the image look right.
Probably can achieve somewhat closer to what QMC GI can produce.Btw..MLT is equivalent to preset #9 for TL
-
So, I've done some adjustements, in the meantime the girl has gone, I'm sorry
raw KT view plus light flares added, I'm gonna work on Gimp.
I thought back to the environment reflections, I'll keep just the light coming from the spherical sky, I've seen the scene also from another point of view and I believe it's ok
-
The render has become much better although I do miss the girl. The interior, for me, just needs a touch more pop. I have done a little post processing on your latest image to illustrate what I mean. Good work by the way.
-
Hi Roger, thanks for your suggestions once again. I like your version, there's another point of view I want to render (time permitting...) surely I'll take it into account.
Luca -
here is my last attempt...
-
The new view made me notice that the perspective is off. The vanishing point is somewhere in the middle of the water. It should be on or slightly above the horizon.
-
not a thing escapes you! You're right, I noticed the sea surface was bended but didn't realize the background was too high 
...one more lesson to learn tridem... -
this is a scene wich I've been played around for a while, now I'm just fed up with it
-
I think your renders need a lot of improvement. Specialy on the light and the
textures. You should also not ignore the basics of furniture construction.
-
Since I don't think is all scrap, please be more detailed on what you think was wrong in order I can try improve it... wich texture? and wich forniture? eg the left part is almost exactly my living room
-
Let's change subject...I did this scene some months ago, but I'd got troubles with the steel brush mapping, now I believe it works somehow

Nice! I think the brushed metal works very well. I don't have any place giving critic because I am not anywhere near the level that you are but I will say this anyway. Just because I have seen enough of your work to think you could do it pretty easy. The plug on the usb seems too perfect. (If that makes any sense.) For some reason my eye keeps getting drawn to it. Perhaps too smooth...not sure. It is just such a great render its a shame to be distracted by it. But like I said...I certainly couldn't anything like this...so what the hell do I know.
Love it!
-
thanks Jeff for so many compliments
You're absolutely right about the plug, I set a bump map since a metal sheet cannot be so 'flat' as a mirror but something has gone wrong and I did not figured out why, I get often problems with UV and scale settings in Kerkythea, expecially with the procedural bitmaps -
The last render is by far better than the others. The brushed metal material does look nice. It comes off as a brushed metal with a clear coat which is believable. The plug material is a bit flat. Typically this is aluminum and has quite a shine to it. Also try putting some vertical scratches that will give the effect of use. The vertical scratches should be faint but there none the less. The keys are well modeled but have a few issues. The are not laying correctly to me. The tips would usually be touching the table. The material is spot on except for the last one (farthest away from camera). This one is a bit blown out. The table material is not adding to the render as it is reflecting too much. Maybe a wood material which a blurry refelction of something like that would work better.
All in all this is one of your best and just needs some small tweaks to make it damn near perfect. Good work.

Hi Scott, actually I wanted show it like some brand new product rather than a realistic one, so I don't agree about the scratches. Also I like the reflective surface very much.
About the laying of the keys I know it's strange, but I worked around for a while and cannot able to find a better position, I should have been using sketchyphisics to solve definitively.
Thanks anyway, I really appreciated your comments

Did you apply any anisotropic scatter to the brushed metal? Don't feel bad if you don't know what that is, I had to look it up too. Aniso means unequal and light hitting a brushed surface will be scattered further in a direction perpendicular to the direction of the brushing.
I also had a problem looking at the USB connector. After checking on some around here, I observed that the corners should be square on the inside and radiused on the outside. They are made by conforming a flat sheet of metal around a very square edged mandrel. The inside of the connector takes on the square edge and on the outside the metal is stretched into a radius. You also need a hot white highlight along the top left edge of the connector which would indicate a radius rather than a sharp edge. I think KT will let you mark edges to be softened or rounded. If not add a white streak in Photo shop. You might also want to add a soft whisper of color (a color different that anything directly in the render) on the upper surface of the USB connector. This will indicate it a reflective surface showing some object off camera.
One way to see of a knife is truly sharp is to hold the blade under a point light source. If you see a long white streak on the edge the knife is dull (the light is wrapping around a radius). If the knife is razor sharp the light streak will be minimal or nonexistent because there is not enough surface at the edge to raise a reflection. Your connector has a knife edge on the outside.
What scale are you working at? One-to-One? I would suggest multiplying all your measurements by 10 or even 100. SU will never be able to do the small radii. I am working on a project with a lot of small parts and SU does not deal well with things in the under 1/4 inch range.
