This is a little stone house located in Istria-Croatia…
The hause isn’t nothing special in architectural meaning but natural materials were used such as: stone, brick, wood…
On this project I’ve been doing several tests with caustics…
The waterpool for this house was done in Canberra… he, he, he… 
I’ve only adjusted the work with caustcis and vraysun
C&C welcome
WHOAAA… SUPERB!!! :shock:
really love the rustic feeling… the stone wall, terracotta tiles, the deck floor… … incredible…
I just think the pool is a bit too saturated… but what the heck… it’s great picture!
Wow, that turned out looking really nice 
The timber decking looks great!!
One slight adjustment I would make however is you can see some of the caustics are hitting the lower windows and causing the light to bounce of and light up the ground there. Looks abit of given its not happening anywhere else.
So what you can do is change the direct light so that its hotspot is square and not a circle.. then you can just fit it snugly around the pool so your not wasting your caustics subdivs on those windows 
Did you stick with vraysun and vraycam?
What color mapping did you settle with?
Any post work?
Well done, turned out great
Excellent!
I just love that pool! Was it all done with caustics or did you fake some bits using maps?
inst there a scale error in your natural-stone wall? fells like they a too big.
mcvltd:
The caustics are proper vray caustics. I gave him a hand with that
:shock: :shock: :shock:
Please, please, please share your settings with us!!!
Thanks guys for comments, really really appreciated…
bluescreen2: maybee.. but texture is done from photo of one existing stone House, so is nearly in scale…
mcvltd: Thanks!.. water is done with caustics, no faking it…
DaForce: Caustics is done with vraysun, no direct light… vraysun has only photon emiter radius…Reinhard color mapping, little saturation and sharpen in PS and thanks for help

2 and 3 Images is done using vray DOF…
Excellent, so the photon radius actually works when its not linked in with a daylight system. Great.
Good to see it worked so well
Maybe you could remove just the windows from the caustics solution. (in the vray properties for the glass)
Might be an option if you ever need to rerender it.
lovely reders, make me want to go to a travel agent and book 2weeks of holiday in Spain …
DaForce: …yes worked good after spending lot of hours to investigate this …
next time I will exclude windows from caustic solution, because this is the end of the story for this House… but this is real coustics bouncing from glass?!

I’m sorry, i’m a little confused by all this, what are you refering to?
I understood that you used a Daylight system with a VraySun.
What do you mean vraysun has only photon emiter raidus?
You made the photon emitter radius cover only the pool?
You turned the sun off for illumination, and only for generating caustics?
sorry i’m confused…
Or maybe you mean the only option to tweek with a VraySun is the size of the photon emit radius (which you set to cover the area of the pool / scene)?
your renders are really nice - the ‘in water’ shot is stunning. great work.
Sorry, let me clear that up.
WHen I was intially helping him with the caustics he had the vraysun as part of a daylight system, and the photon emit radius doesnt seem to work in that situation.. Vlado???
So i had it setup with a direct light for caustics.
He has now just used a vraysun by itself without the daylight system so that he could use the photon emit radius… which is set just big enough to fit the pool.
that stone wall texture is too bright for me. its too bright in shadow and too bright in the sun. i would turn down its rgb mult by a good 10-15% and see how that looks. everything else is very well done.
sv: Everything is explained by DaForce…
thanks DaForce

ahhh right… bug then?
I believe so yes.
…ups, I’ve forgot to answer on percydaman’s suggestion
I agree with you but the Client wanted brighter stone wall…
nice looking images!
a little too saturated imo…but great nevertheless…
so thats why caustics don t work for me! damn!
In 2000x1333 px is less saturated
