Here's a try at 1.0 - seems like the beta quality is back, light transport/color etc looks *really* accurate, took a hell of a long time to clear up, though - probably my ignorance of the new material system, will try to improve...



Other stuff done with the trusty beta:







Cheers

Very nice, love the light

Good start on your composition.

The triangular shadow under the left side of that open credenza looks totally black to me.

the second image [with the evening light] is way

I really like the maquette ones, especially the first one (and those paper clothes are brilliant). too bad they're still a bit noisy..

beautiful! I really like the 2nd an 3rd, those are brilliant...

good job!

Hey, thanks for the kind words all, as always

@Frances: Yep the black shadow is strange - here the problem was that all reflective mats were done as two weighted bsdf layers, one lambertian with the texture and the other more or less a mirror (this was done because a single bsdf with low roughness was always coming out too black with the nd value). So more or less, all the reflective surfaces were done by eye to get the right effect (by balancing the weights of the two layers), but its hard to tell how that reflects on reality/or scene light distribution - the overall effect is ok, but not quite sure whats going on with some of the surfaces



For the noise, dunno, those mockup scenes ran for about 10 hrs before before sent out, then kept running for another 10, but the difference was minimal...might need to run them alot longer

DOF!

the problem with a real world simulator is that in order for things to look real they need to be the same scale as the real world. Camera lenses behave differently regarding Depth of Field depending on how far things are from the camera film plane.

I would be willing to estimate that your chairs are about 6 inches tall, and that the distance to the camera would be a couple feet at most.

You need to ensure the scale correct and that the camera is at least 10 feet from the chairs/tables. If you were to take a real picture with an film SLR/50mm (close the the field of view of your eye) you would find yourself 10-16 feet away to frame it the way you have. At that distance it's almost a physical impossibility to get that dramatic narrow area of focus with such a smooth transistion to out-of-focus. You MAY loose SOME focus at 30ft+ and you would have focus up to about 4 feet from the camera.

Another point is that as you get further away from the camera, say 9 feet the DOF 'appears' to shift from focus to non-focus much more abruptly. When the objects are only a few feet from the camera we get to see gradual change from focus to out of focus... when something is 12 feet away, that shift is much harder to see, so in fact you would have one chair in focus, and the nearer chair would be half in focus, half not. the gradual change we see tells us the object is very close to the camera.

check out this link, it outlines the basics of DOF, ALSO includes a very handy DOF calculator which can be used to estimate if your level of DOF is realistic for the scene's intended scale and your desired distance from your point of focus.

um, I guess you would be right then, because those are not full size chairs, but renderings of a maquette.

Uhhh yeah, that was kind of the point (maquette), but thanks for the info iandavis, I'll check it out and see what i can learn. Cheery!

Hi aitrazz,

On the 1. image the ceiling 'looks' evenly out of focus. Is it just lack of detail?
It looks strange because the lights are so well defined.

Love the 2nd image

LOL... ok then... I guess they are perfect then!

hehe
