I'm setting up a clone (almost) scene and I need a good advice on Ceramic Material glossy as no matter what settings I use I keep having too much noise to sort out even at 16000 samples
considering the scene only have a flat white diffuse ground and Ceramic material with HDri as a texture environment. will post a quick picture about it

Hey,

A screenshot would indeed be handy...

indeed...cooking up

Here you go, actually I think I managed to find a good blend for a decent rendertime at 8000 samples,only despeckle once on Photoshop but you can see the panel image the noise is almost gone apart from some areas inside the mugs, it's a clone of an image that did strike me from Surreal Structure part of the Fryrender gallery.
I should start using nodes to create materials as I'm quite confuse about some values like the roughness value, the slider looks 0.00 all the way to the top with only 0.07 and 1.00 wish I can save them...

I may post this in the gallery?

you should use this technique: http://www.refractivesoftware.com/forum ... f=21&t=878
and it looks more like plastic than ceramic to me, but i've no idea what kind of ceramic you're after

do post it in the gallery, but i recommend the supersampling technique to get a better result.

Thanks, if you look at the image that I mentioned you understand what I did try to achieve, I know by experience that ceramic is more glossy than this set of mugs but in real (like my mug were I'm having a coffee right now) could be anything and I think that I should add some sort of noise in the material slot to add some imperfection to the ceramic material itself...hard to explain, I know the technique but I wanted to start balancing rendertime VS quality etc... still just 2 months ago I could only dream of start using not even the edemo of an unbiased render engine for such images...thanks

Once we got MLT and materials depot sorted out would be 10 times exciting than now..and I'm having real fun......
