Hi, you can use the unpack option in the installer. In the unpacked folder, you will find a readme file explaining how to install Corona manually.
If you continue to have some problems, please contact us at https://support.chaos.com/hc/en-us/requests/new

Can you show the top of the VFB window where it says what is the current rendering resolution? Also, can you share all other render settings? Are you by any chance using upscaling?

My argument against setting any denoiser as a default would be that most likely you would get flickering when rendering sequences.

Corona defaults are supposed to be safe and with as little bias as possible while keeping reasonable render times.

Also, consider these posts:

There are limitations though which aren't obvious:
- Complicated shader trees tend to resolve detail (bump, procedural details in noise maps etc) at a later stage in the render progress. With only a few passes the result will be less surface details.
- Some of Corona's sampling-based maps like AO and Curvature will also refine at later stages. I got some heavy differences between the two images where AO was much less pronounced and detailed in the downsampled image (with less passes). If you're using those kind of maps, it's best to still allow more samples.
- Refraction details also tend to take a bit longer, so you trade sharper details (implying more detail) for less actual detail and accuracy.

(...)We're finding significant detail boost at lower passes using this method, and that's without actually rendering at 2x scale and downscaling back down.(...).

So maybe that video isn't as revolutionary as it sounds. :)

I guess Tom accidentally edited your post instead of quoting it. Happens to the best of us! :)

If you have any scenes where the issues can be reproduced (for example the "no sky" or "no objects"), please contact us here and attach your scenes: https://support.chaos.com/hc/en-us/requests/new
Thanks in advance!

As a workaround, (perhaps) you can use a Corona Physical Material with self illumination.

Exactly the same as with production render:
Add the AiEnhancer multipass > start IR > make sure the rendering width or height is no less than 512px and no more than 2048px > click the AI Enhancer button in the VFB

You can paint different vertex masks on different channels. Then you can use Vertex Color maps in the material editor as multiple masks for your materials.

Sorry, but we cannot provide you with support for such an old version of Corona. Very likely, the issue is already fixed in the newest version. Please download it and check if you are still getting any differences: https://my.chaos.com/download/build?product=Corona

thank you for your answers!
    I have often (systematiccally, in fact) the pop up: "chaos unified login application is not running".. i press "refresh", but without success... the access to cormos browser is ok, in the same time..  how to solve???

There were similar posts in the past. Here are some ideas:
- Make sure you are not using any overclocking
- Make sure your RAM is installed according to the motherboard manual (like AABB or ABAB order)
- Try disabling hyperthreading in BIOS and see if it changes anything
- Check these advice by Juraj - https://forum.corona-renderer.com/index.php?topic=25697.msg159991#msg159991

Also, in theory this shouldn't be a problem, but this CPU is now almost 7 years old.

There are some artifacts in some of the images. For example this one: https://forum.corona-renderer.com/index.php?action=dlattach;topic=45124.0;attach=211282;image
Did you use the Intel denoiser? Was its amount set to 1? Did you switch to Tent filter in Render Setup > System?
