I'm running SKIndigo 2.6.1 on WIndw 7 64 bit , I7-920 , 12 GB Ram , GTX 580 Graphic Card.

for this simple kitchen rendering , it takes about 9 hour but only have a result like this.

whats the problem with the frosted glass material still so much noise ?

is that any way to settle the above problem ?

Also try without glass acceleration. It can help only for flat specular glass (such as the window) and not for frosted. Also, I'm not sure it is useful for indoor scenes with portals.

Probably your whites are too white, and you're not using MLT.

Glass acceleration doesn't work well with exit portals currently :( However, when you're using exit portals it's anyway more efficient than GA would be.

Etienne's advice is spot on: try without glass acceleration (but still using bidir and maybe also without MLT).

BiDir MLT or MLT+PT?
BTW, quite good result! Good job!

..only thing, I see too many sharp corners... SMOOTH SMOOTH SMOOTH!

Very nice :) Love the tones.

If you'd square out the composition and add accessories and some more 'lived-in' detail, it'd be a great shot!

Good advice here. I'd also change the texture mapping on the large wooden frame in the right part of the image. The texture should run vertically on the vertical parts and horizontally on the horizontal parts (not sure I explained that well).

Sorry pibuz.. the reason i let the model square edge is because i need to do another details works with LayOut
that's why .. if i use the soften i cant get the edge point in LayOut.

or you got a better idea for me ? :|

i hate details works!!!!

I didn't mean "soften edges" :lol:
I meant: use some cool plugin like roundcorner.rb to get less sharp 3D edges: they will result much better in the rendering..

..Though, you still may not see them in layout.. :?
