looks great, maybe wood is ugly in this scene (for me too big texture strench and colour) and maybe to small contrast (but don`t down Parametr - much better is smaller POWER in Kray Photon Map (maybe 0.5 or 0.6)... wood have too small bump and too big blurr.

I thing You look this:

Thank you

Yeah you're not wrong about the wood, I think I have to improve the map on photoshop and decrease blurr.
About the color, it is quiet as good as in reality in fact...this is Hermes specifications. Take a look at the pictures...
It also has no bump (polished).

About the contrast I don't know how can I do since I already have 0.5 power..

What is Irradianceblurgamma for??

And about your exposition modified proposition, I have to stay to hermes store specifications, it meens warm ambiance is needed as in reality.

Irradianceblurgamma holds samples in corners. (0.3 is good)

I can't believed the first render and the last render in the post were done by the same person... the final result is fantastic!!!
Congrats for the nice final image.
How did ur light setup change from the beggining? Any screen grab from Layout?
Cheers!

Good to hear that! I'll try to do some more soon. Do you guys have any suggestions about the topics you wish to be covered?

Well... I just purchased the software recently and I have been watching and reading all the different tutorials.
I would like to know the different ways and steps that for example you took to get this final great image. I am
an experience lighter within architectural viz industry and decided to purchased kray couz I have been using Lightwave for
so many years but I am starting to do some more often freelance jobs.
I have used extensively maxwell but I always wanted to give a try to kray.
I just got real basic questions as I started yesterday my first image and I am not sure whether to go for light mapping or photon mapping or if we can get final results just using Photon Estimated mode, instead of Photon Mapping mode...

I'd say in 99% of cases you'd want to use Lightmap. Photonmaps are useful in situations where light is coming from very small, hard to reach places. Photon Estimated mode is not meant for final renders because it will not render nice indirect shadows. It's just a quick approximation method to evaluate lights and materials in the scene and check to see that photon map is not too splotchy because that can throw off FG calculation later.

I've recorded this quick video yesterday. It shows typical workflow for interiors.

Thats fantastic!
I will try to post some images in the next couple of days with the stuff I have learnt to see
if you can give me a hand.
Cheers!
