actually looksreally nice. I would preffer some oiled oak flors with this furniture & that type of rendition /going to hi key side=).. but it's just a matter of taste at the end =)

Mind to share numbers to ilustrate resolution & render duration/ cards You've used? =)

just a quick dirty attempt with no texture on chair and table. More to come
30 mn at 1600 px with 2 quadro 4000 (slow in comparison with titan :roll: )

That looks really nice :D although I find render time is a bit long. I usually don´t need to let it cook for more than 20-30 minutes in simple scenes like that. And you´ve got 2 cards working... maybe you wanted to make sure the noise is gone.

Hi

So AO in directlighting is a good way for final renders ?
I often read advises for using PMC or pathtracing

(sorry for my english)

for me if you've got short deadline the "AO" solution is the way to go with some photoshop.
But I'm working on a more complex scene to make a comparison between the 2
The directlight mode 4 is very interesting too :)

For my experience, there are situations where you cannot tell the difference between AO and PT/PMC, specially when there are little occlussion, such as exteriors or studio shots.

You are talking about the diffuse mode, I think (direct light mode 4). If you don´t need caustics that´s the best solution. Diffuse mode is the same as PT/PMC, excepting it hasn´t got caustics. If you want caustics, go for PT. Use the PMC kernel in hard to sample scenes, such as little emitters and the like.

An advice to make nice looking wooden floors: Use a b/w version of the texture as a specular map. You´ll get much more convincing and natural reflections. Not using this trick can cause the wood to look like a sticker pasted on a vinyl.
