First thing you should check while converting your v-ray scene to corona, especially when you're using material converter and not doing it manually is to check all your transparent and translucent materials that their refraction mode is set to Hybrid (for solid glass) or Twosided (for single sided glass like window glass etc.) modes ( http://clip2net.com/s/6DRyHE ) this way http://clip2net.com/s/6DSz9a you can get rid of those nasty fireflies way faster, cause corona will not calculate caustics for those objects and caustics for interiors are just plainly unneeded :) (in most cases) - people hadn't written about it for one simple reason - in dailybuilds it is set to be so by default and most of them are using daily's for quite a while and have just forgot how it was "back then"

Thanks a lot Antanas. Now I'm rebuilding the glass material of the entire scene to make a test.

I appreciate your comment.

Cheers

The problem is that you have tried to convert a Vray scene without knowing much about how Corona works. Conversion is never a 1-click process. You will get errors and slow downs. The scene you have posted should not take anywhere near that amount of time to render. Other users on here are putting out amazingly photo-real 4k renders with zero noise in about 4-8 hours.

I suggest you read Rawalanche's post on how to use Corona properly in this thread http://corona-renderer.com/forum/index.php/topic,2518.0.html

For that reason I need help. (And I think a lot of people are in the same situation like me)

I think this is good idea. If anyone look at the graphic bar in this thread (http://corona-renderer.com/forum/index.php/topic,88.0.html) can realize that the vast majority is coming from vray.

I think a PDF or a organized document for the conversion is needed.

Thanks for the the initiative.

Like DeadClown said, looks like in your image most noise comes from direct light (there is no noise in dark areas) so you can try raising LSM (light samples multiplier).

Thanks Maru.

Yes, I made some changes. Fist, I delete my IES and put a Light material in the spots, and second, I increase the LSM to 5.

But for this render, I wait 21h in my i5 and it takes 127 passes (3500x2475px)



I think Its not very useful in render production for my. But anyway, a put another image to find the corret settings for make it more faster.

Some time ago I buy a license for Maxwell render, first in beta process and then I pay the upgrade to 2.0 version. But I never  use it for the same reason, very slow, and imposible to find the correct setting for a reasonable speed/quality images for production. I only speak for my personal experience and my self.

Its posible, or very dificult, to make a presets library and integrate it with the release for the common situations? You now;
low quality, draft, interior, exterior ... like solid rocks for vray. Then you can change all the setings if you want.

Is my humble opinion, and a lot of thanks for your support.

(Sorry for my critics, and my bad english)

Yes, you did change msi - don't. ;)
Try setting max sample intensity back to 20 and render again.

Thanks, now its rendering with MSI=20, portals, and colona IES lights on spots

When it finish I show you the render.

It may be also solid glass covering those lights ;)

Yes, I put a solid glasses for my windows

I guess you're simply having fireflies from the extremely bright lit lamp-"holes" in the ceiling (not the lightsources itself, the geometry around). Did you change msi?

There are my render options of my scene




Try to use emissive planes in the spots! no lights! it will work better :D

Ok, goog idea. It's not easy because de wall is curved, but, any way I try to do this and post more images with the new settings.

Thanks for your support!

Hi, Im a 3D artist, and a try to convert my workflow from vray to corona but its hard for my.

I'm not sure if this message is in the correct place, if not, please move. (sorry)

I made this interior scene in vray for test de conversion to corona.


Ok, its not a great image, but I need to start from some point ...

and this is the corona solution.



Ok, is not the same ilumination, but is 122 passes and apears a lot of white dots.

What's the correct parameters for a good solution?

Now is PT + HD in Prograsive mode.

Thanks!

Excelent work. I love the BenderĀ“s one :p

No, I don not see nothig ...

But now, I put my forest objects whith corona render active, and my materials apears like vray mats. Then I aply your script and works fine ...

I don't know what's wrong in my other tests. Now works perfect whith your system.

Thanks a lot!

Cheers

Is posible convert forestpack materials?

I try this, but the scrip don't respond.

What do you mean with "don't respond" ? The script normally runs very fast, so it shouldn't be taking too long.
The problem with forestpack is it's material slots. If you use an object in max as a geometry input in forestpack it's just fine and it uses the the material from the node (which will be converted). As soon as you drag a material to the respective material slot in the forest object it seems that it's not counting as a normal scene material and I got problems converting them. Same thing happens if you're using something from the library. Clear the material slots to force forestpack to use the node input material and everything will be converted fine.

At first time I try to convert standard mats whit your script, and take a lot of time. Then pur Vray like render engine and try to convert the vray materials, this option take very low time, but the material conversion don't work fine.

Thanks, I try to make  your option.
