V-Ray GPU not working at all.

[rodrigo_sotero]

Hi guys,

I want to share my issue regardind to this topic. Today I had the same problem, all of a sudden the VRay GPU render stopped working after a 3dsmax crash.. I thought maybe some chaos server file was still loaded into memory and was giving this glitch...

But then I thought looking into the Log file.. and for my surprise the last error was:

[2024/May/26|17:23:36] warning: Could not use any of the selected (1) hosts for distributed rendering!
[2024/May/26|17:23:36] error: Local machine is not used for distributed rendering and no servers can join!
[2024/May/26|17:23:36] Max ray intensity is enabled: rendered result may have incorrect brightness.
[2024/May/26|17:23:36] [VRayRTMax::Render()] Cancelled before render​

And I was using just my RTX4090.. never touched the Distributed Rendering ON option!!!! So maybe a bug, maybe a hidden shortcut I might be pressed and it just turned it on... I wanted to share this so the devs could say if there is such chance for this option be enable by accident..

So other than that, it was just turn this option OFF, and the GPU render get back working again.. Yet using the latest Studio Driver v.555.85, and not the recommended version stated at the https://www.chaos.com/vray-gpu page

My best,

Hi Rodrigo!

Did you use the Vantage Live-link?
It is usually the reason DR could be turned on

On another note, we will be updating the GPU drivers soon. We are testing this now

Hi Muhammed! Thanks for your reply.

Yes, I was using Vantage most of the time, but since my shaders was using both VRayDirt and Curvature, and unfortunatelly Vantage still won`t render both of it, I had switched to Vray GPU.
So now I know that thats the culprit of turning DR on, thanks for the valuable information!

Do you have an idea of when we will have Dirt and Curvature being rendered with Vantage?

My best,

About Dirt and Curvature, they are on the roadmap for Chaos Vantage, they will be implemented at some point(not this year), although Dirt will probably affect interactive performance considerably

Great, having curvature would already do the trick for some things.. Since we now have displacement, I`ve been using Vantage more. ^_^

Let me ask you about SSS, I see that FastSSS2 is there at the docs, but I still can not make SSS work with Vantage... is there any trick on how to render SSS with Vantage?



Thanks

Hi rodrigo_sotero

SSS is still not implemented in Vantage, and we haven't decided on which SSS model to support in Vantage yet. It is on our roadmap to do, higher priority than V-Ray Dirt and Curvature

Muhammed

Thanks for your reply, @Muhammed_Hamed . Those are really some special and important features to exist in Vantage, would improve a lot the final results of our projects.

I'll be waiting for it

My best regards,
