Really nice Polymax, you’re quite close to the VRay version, closer than me 
I think i had a problem with the shader of the furniture and on the reflexion of the floor, so that’s what makes your image better.
Congrats (maybe too much noise for the final render here ?)…
@Roland… it seems there isnt any difference in speed btw v5 and v6? but your post work is amazing:D .would like to know you process pls? or anywhere(link) i can get a step by step tutorial perfect for interiors?
@Rawalanche : yes you’re wright i think there is less noise with the A6 but for me it’s not a great difference. Maybe on an other project…
@yagi : thanks for your commentary. Well my first desire was to clean up this awful blue sky. It was a demand of my customer but I didn’t like it, so I did a post-prod image for me !
I used some known process and scripts in Pshop : a little more lighting from the exterior with Rays (https://www.digitalfilmtools.com/rays/) and a big work with some filters : Levels, Hue/saturation and a big “brown to gold” gradient map.
Then I have Corona passes, Texmap was the most important.
Here it is ! I can’t say anything else because I did not keep the final PSD, just wanted to quick post this difference between A5 and A6
If you need anything else don’t hesitate !
