Great!! But maybe a white plane behind camera could help! Im not talking about a emiter, just a white plane, so that light has somewere to bounce on and hit the juice box.
That could greatly improve those render times and reduce noise.

Other than that, this already looked promissing on your first post about it... It can only get better :wink:

yes rendertimes killed me on that one... he he.. a white plane you say.... hmmm, but there is a wall behind the cam... it is surounded by a wall, alsoa ceiling...

from small tests I did, it looks like it would "maybe clear at 23 /24, but I did not want to wait another 20 ours just for a test... he he..

Thanks for your input... :wink:

The image is extreamly noisy on on sample 21!
How many blades have the camera?You can try to lower it and get nice hexa,okta bokeh reflection.

Still looks cool. ;)

But way too noisy for lvl 21. :( Maybe too much plastics in your interior, It might wort to check how fast would this clear out with only diffuse shaders applied.

Btw, that oven back there with the sink looks interesting, don't you want to put the camera a little closer to them? :)

:: Herve... any chance you can tell me your material settings for the kitchen top... i am working on something similar but mine has too much gloss ... i appreciate it :wink: ::

Herve (sorry don't know how to make the accent)

I find so far that Maxwell becomes very noisy when not enough light is involved. I would make a hole in your wall directly opposite of the window... then another hole on the wall behind the camera. the size of the hole will dictate how much extra light enters the scene.

In my experiments once some magical threshold is reached one can get to a decent image with 10-15 passes. (see example image rendered for just a couple hours and 11 iterations)

physical sky, without sun. No emitters.


cheers.

hey thanks... sorry for not answering earlier, I have not see it...

@Psanitra... indeed super noisy... I guess NL will have to implement some sort of trick here... I have the camera set to circular, the other has been removed for now by Oscar (he said it..)

@Aldaryn... thanks ! well there is some plastics, but only where it needs to go... walls are diffuse... I think the bottle neck is with te SSS curtain... I'll try without it....

@X-Site... I'll check and tell you in a hour... (it is on my second computer..)

@ IanDavis.. hey Ian... you're right.. but I was testing a bit to push MWX and see where can I go... if I need...

Nice render Ian... is it a voting machine...?

Herve,

It's a library machine, where users automatically checkout books.

:)

If you do re-render that kitchen with more light or different surfaces... be sure to post, I'd be curious to see the diff.

cheers.

I made all surfaces pure white... with default diffuse... hummmm

level10 in approx 35 min. err... Houston... sorry Madrid...

BTW X_site,

Color grey 30 %, Plastic Mat (0.4 UV rough) and 65% grey map in spec channel... that's it !

Herve,

I have a similar problem with a project I'm working on, if I use diffuse white for all the objects (trying to get light levels right before I texture it) I get a fog like your image. Does anyone know what causes this?

yes, pretty bizarre... and it started even worse... :cry:

Don't make the diffuse too white, keep it at 230-240.

ok, let's listen Mihai, and give it another try...
