[joto]

guys i set high quality render setting have still bad reflections on the water surface, chrome edges, roof and the floor stones.

 

what is the problem here that i can't get nice reflections even this high settings?!

Hi,

1. First of all, you simply cannot leave Irradiance map on low settings. Make it at least medium, maybe even high, default 50/20 or higher if needed.

2. You could also raise up a bit Light cache subdivison, and make sample size a bit larger (0,02 or 0,03), it will be smoother and less noisy.

3. If you want strong and clear reflections you don't necessarily need to use Fresnel (I saw one texture with Fresnel IOR 50, dude what the hell was that?). For clear, shiny, highly reflective surfaces you can freely use standard reflections, tweak it a bit or add falloff map to simulate Fresnel if you really need it.

Try all of this to see if it made the diffrence

thanks dear,

 

but it doesn help.

should i send you the scene without much models to have a look on it?

 

thanks!

The problem with your reflections has nothing to do with your render settings so set that aside for now. Regarding your materials, chrome/polished SS should not have Fresnel activated. If you turn that off, those materials will reflect as you expect - mirror surface.

For the water, get rid of the glossy reflection. Water is not glossy. For an indoor pool that is empty, the water surface should be perfectly flat.

Switch your refraction and reflection IOR values. after that, I would recommend using 1.01 for refraction. It's not technically correct but bent rays look strange to most clients so faking it will make the pool depth look like what the client expects to see.

Get rid of your fog color as well. unless you have dye or a poor chemical/mineral balance in your pool, it's gonna be colorless. If you are set on coloring it, be very conservative with that if your water surface is a simple plane. start with something like 245,254,254 and the multiplier at around 2.

 

your scene lighting overall needs work but I suspect you know that and are still working on it. The flooring and ceilign actually have a pretty nice feel to them so I'd leave those alone until you get your lighting worked out

 

The candles look good though their placement is not a very good idea. having had to clean up wax from floros before, i always put those inside lanterns now or up off the floor in holders.

It's hard to tell much about the furniture from your intentional blur but they look very stiff to me from what i can tell.

 

lastly, having worked on designing pools including a former olympic venue, I can tell you your coping and gutter system needs attention.

thanks all, but the main problem was the big light emission from the roof lighs, after i turned it off, the reflections was gone off.

i think this is a big problem to have big light emission from up side.

i tried your material suggestions too, and i got better results.

 

now i have to see how can i even have big light emission from up side and have even good reflections!

 

thanks all
