Hi!

The image attached is a bottle with blurry reflection, at 80 percent blurring. The lighting is done with luminous polys that are invisible to the camera, but are seen by rays. The problem is that there is a lot of noise in the bottle surface as you can see, even at "high" settings, giving the impression that the surface is rough or sanded, while it should be perfectly smooth and matte. Maybe a tiny bit of noise would be okay, to give a satin finish, but this is too much noise.

Is there any way to get rid of this noise, without having to crank the settings up to one gazillion rays? Some specific setting or maybe even a special header command?

Thanks,
Thomas

Show Quality Tab from Kray, please.

Sorry, that was a stupid question. I just needed to set the min and max number of rays for reflection higher. Perfectly logical, so I should have known that!

Thx,
Thomas

sorry i can't render with this problem...noise in reflection blur.
who can help me?
i need of surface with reflection + blur...this result isn't good!!!

i've used uncached but the effect is this!!!

200/600 is too less. Try 500/1000 or 500/2000.

with 2000/5000 no problem!!!
thank's

Please notice also this: If You use high level of quality blur (2000/5000) this means You have probably too strong luminescence..... I try keep maximum level 500/2000.

I think min/max for Area also is too high. Personally I use maximum 2/4 (for fast preview render: 1/3)

thank's Janusz for explain
