Thanks a lot for your replies...

So my guesses were right, this image is too noisy and slow.

Let me analyze the image.

Rays per second
1444000
(I don't know why, in my previous render were higher, like 1800k)

Rays/sample 85.9

HDRI in the background, Reflection panel (no direct lighting) in some places outside.

IES - CORONA IES

The floor material is quite simple,
see the screen shot.

There is something I could do with the settings ?

Hello to everyone.

I know this is a very repetitive question, But I'm starting to use Corona in production and strongly want to understand well how it works , and how I can achieve "clean" images in reasonable render times.

Please help me if I'm doing someting wrong.

I'm doing an interior retail . Lots of clothes, lots of instanced polys.
HDRI lighting (with a dusk map) and interior plane lights.
some ies here and were (less than 10 in total)

In a 1800px X 1000 image (so not very high resolution) after 3 hours I still have lot of noise, expecially on the floor (quite simple material, glossiness at 0.7, small noise in the reflection slot)

I use ppt + UHD , LSM 4 and GI/AA 32. Internal resolution to 1
I've lowered the MSI from 20 to 15, in order to have a bit less accuracy and less noise, but seems it does not work.

The windows glass are thin...

I am doing something wrong?
It's normal to wait more than 6-7 hours to have a clean mage with this resolution?
My pc specifications are i73820 with 24 gb ram (I know, I need a serious upgrade...)

Thanks in advance for any advice
Gabry

 
The noise is mostly in the direct lighting

I've read lots of articles in the helpdesk....  but I can't find the right solution for this kind of problem.

I've raised the LSM to 4, but nothing happened.

The glass in front of the windows display is a thin glass.

I've put other corona lights in the display, but it's very hard to kit evenly the display.

other suggestions?

thanks in advance

Hello to everyone...

I'm trying to make the total switch from Vray to Corona, and obiovously i'm facing some problems.

here there is a "slice" of a night rendering. Light by hdri (environment) and  plane corona lights in the displays.

I'm facing LOT of noise in the small displays. The rest of the image it's pretty clear, but the noise does not seem easy to be cleared...

I'm lighting those windows displays with one plane corona light at the top (that struggles to light properly the whole windows... perhaps I should use some ies lights, instead)

How I could achieve a pretty uniform lighting?

thanks in advance..

Thanks again Juraj :)

I like a lot the thing that they do not alter the amount of light... In vray was a pain...

now it's time to go back for testing :)

Thanks so much Juraj.

I've read (and heard) that I could use the VrayHDRI map, and I made the error to think that also the vray dome light was supposed to work.

So Corona does importance sampling also from the environment slot... instead Vray needs the dome light...

To improve the light solution (less noise,  faster result) , I should use portals in every windows?

In vray skyportals add lot of rendering time...

Thanks again
Gabriella

Yes, but...

Why I read lot of people using them... and I simply can't make it work?

I'm trying to learn the program...

thanks again

Hallo.. please forgive this probably stupid question, but I've searched  the forum with no luck.

I'm starting to use corona, and I've started do study the sample scenes.

If I try to use a vray light dome with vray hdri, the scene goes completely dark.

I've deleted the corona sun and cleared the sky from environment. Added the Vray Dome... and It simply does not work.

 have I to activate something? I can't get it work...

I know I also could put the vray HDRI into the enviornment slot, but I've read that's It will get less light samples...

thanks in advance
Gabriella
