Black dots

V-Ray V-Ray for 3ds Max Issues
1

Hi!

I’m having this problem with my render i can’t seem to figure out, i’m getting all these black dots all over my render.
I’m using VraynextGPU, progressive (coz bucket just seems to hard crash max with this scene), the scene used to be redshift, but i replaced the materials, merged all the assets into a fresh scene and did a scene convert to make sure nothing RS was left
Furthermore there is environment fog in the scene and Ornatrix, but the dots appear even if i render the scene with everything hidden.

The dots become more numerous as the progressive rendering adds more passes, and only seems to appear with environment fog turned on.
It also appears when I switch off the GPU for rendering, but it doesn’t seem to appear when i use vraynext instead of vraynextGPU

Anybody any ideas, this is a new one for me.

Is the pixel value of these black spots something weird or even negative?

Can you share the scene to support@chaosgroup.com with a link to this thread and we’ll check it out.

I had this a number of times before. There is nothing you could do, this is a V-Ray bug. To me it always happened either on reflection pass, or specular pass.

Had this issue too in the past with vrayenvironment fog. Stopped using it altogether.

I hope they can figure it out, luckily its only in GPU and not in normal vray, will just take a lot longer to render :frowning:

I looked at the scene and here it seems to be happening in hybrid mode only. Can you check if it’s the same story on your end?

I’m not sure so I’ve logged it as a bug for our dev team to look at and I’ll post here when we have news.
The reference ID is VGPU-3895

Any news on this issue?
I’m having the same behavior now with VRscans using Vray Next standalone
It only happens with hybird mode

@Muhammed_Hamed Nothing yet, sorry. The issue is still open, but I’ll let you know when we have updates.

@Muhammed_Hamed This has been fixed for a next V-Ray service pack.

Send the scene via the contact form so we can take a look.

I have the same issue on Maya 2023, opened up a ticket via the contact form. That being said, I found that adding a filmic tonemap (Hable) in the VFB, fixes the issue. Obviously, I assume we should not have to do this to fix it :slight_smile:

i’m getting black dots with Vray GPU RTX4080. Vray 7.00.02 build 00000. i have not updated my grafx card drivers yet however (current 551.86). but did start using 7 last week. i’m in rtx mode, cpu un-checked.
