The first image

[Wallace Amorim Júnior]

Well, this is the frist image i upload using nxt, but not the very first one i did.

I would like to go deeper in the renderer, but i'm to insecure about the work.

I used path trace ando change some settings. Hdri on the sky, cloudness and sun at 0.5.

And after 8 hrs and only 52 passes, this is the result.

Yes. Refractive caustics are automatic.

Hi, Roy. I'm having problems sending the file. Maybe it's because of the size. 14 Mb
Is there another alternative?

[Roy Hirshkowitz]

I did receive something from you.  The Upload link is usually pretty robust.

Finally got around to this one.  I haven't found anything wrong.  What I thought might be a problem turned out to be a level change in the pool.  Looks correct.  I changed the material a little-- IOR of 1.3 to better represent water-- changed the bump pattern to a shorter period (.6 meters or so).  Caustics are sensitive to the bump and the distance from the surface to the bottom of the pool-- that's as expected.

Thank you very much, Roy. Good to know we have that support in this community. By the way, here is a picture from another point of view of the same house.

I sent the images to the client, and it was approved.
I'm preparing the images of another house for the same client, and when it's ready, I'll post here.
