I'll try to restore previous "version" as attached now ( more brutal with black shape visible on snow ). This is part of the image from today. Please save image and zoom as 200% or so. Black dots are visible in glass and quite a lot of black dots areoun the scene. I added also my current version of Corona.

Eeek! Okay, we see what you mean. Could you possibly share this scene with us so we can investigate it? If so, the private upload link is in my signature below. This would help us very much ;)

Yes, of course I'll share entire scene. Today I was out of my dark deep cave of 3d production :) but tomorrow I'm going to prepare badass scene version for you. To avoid any confusion I'll prepare full 3d data without any shortcuts to restore 100% black dots rendering environment. I suppose that the file size will about 1,5 - 2 Gb.

Hi beanzvision


I'm preparing scene for you but I have make a tests to be sure that black dots will appear. If we play in the same sandbox I have new toy which I could share to you if you would like :) . This time it's night scene and light render problem with environment fog global volume. Please take a look on the picture below. I used global volume fog material and spotted weird artifacts under the streetlight spot. It doesn't look the same always. Sometimes the shape is different. To avoid this again I changed global environmental fog to huge cube which covered entire scene and render works quite fine. Result in this topic:

If you would like I could share this scene too.

I sent first night scene with street lights in the fog artifacts. I discovered which element causes these rendering errors. You will find at the top of the objects list street light instance object. I don't remember why I movet this object under the street object to move it out of camera visible range. When you turn on this instance the artifacts will appear. When you turn it off everything works fine. I'm not sure it it will allow you to investigate something interesting for you or it's just a mess in the scene.
I'm preparing next scene for you with blacks dots. After yesterday time consuming tests I couldn't release black dots again. I tested last scene and also two previous versions from my backups. Definietly I spotted black dots previously a few times during this project but no yesterday. I'll try again and independently of outcome I'm going to send the scene to you.

I'm sending by dropbox second winter scene with black dots problem. I started last test today but no black dots. I couldn't describe which factor release black dots but I spotted them a few times working on this scene. First object is a fog cube mesh. Turn it on and turn on environment global fog.

You're welcome!
It looks like this... I think they will appear during next project with strict deadline :)
