Hello,
We’ve come across an issue where the scene runs fine, until Live Link is started. Then, any change, orbiting viewport, parameter in Material Editor, even opening Render Settings takes 30 - 50 seconds.
What’s weird is that the issue persists even after Vantage is closed. It’s like running it once corrupts something and gradually decreases performance. VRAM is not the issue.
Max 2026, Vantage 3.0.3,
We’ve had a few similar reports in the past. Some of them seem to have been caused by overloading the machine. In your case the slowdown remains after you close Vantage, so it must be the other thing - that V-Ray IPR causes a slowdown while exporting changes made to the scene (it could also be a third party plugin or Max itself being slow while V-Ray is processing the scene). Note that if you simply close Vantage this does not stop the live link (live link is a kind of DR session and enables the render server to reconnect - if you restart Vantage it would reconnect in a few seconds). You have to either use the Live Link button to stop the session or the stop button in the V-Ray VFB.
Does the same happen if you use V-Ray GPU instead, with the same scene?
What is the version of V-Ray and what hardware are you using (GPU, system RAM)?
Can you share the scene so we could reproduce the issue? If you can’t share a public link you could send it through a support ticket, mentioning this topic in the ticket: https://support.chaos.com/hc/en-us/requests/new
Okay, sorry for the delay, busy times!
We were able to most likely narrow down the issue.
Whenever we’re using Anima in our shot, we have to turn the “Use Render State in IPR” option on for the characters to appear. This alone causes no issues.
But it seems one of the assets in our scene had a TurboSmooth modifier with “Render Iterations” > 0. For some reason, when these two conditions exist together, any change in 3ds max, like opening Render Settings, or changing the view from Camera to Perspective, etc. is followed by massive lag in Max.
And indeed it stops immediately when disconnecting DR (not only closing Vantage)
I’m not sure yet whether this occurs only with this specific asset or in general.
I will share the scene using the link provided.
Thanks,
Thanks for the info
Hi Pedro,
Thank you for the files.
We’ve identified the cause of the issue, it’s not related to Chaos Vantage or V-Ray.
The same freeze occurs when enabling or disabling TurboSmooth.
The problem appears to be object-related. After clearing the UVW and resetting the XForm, the freeze no longer occurs.
You can achieve this by adding a UVW Mapping Clear modifier and then using Reset XForm from the Utilities panel.
Please test this on your side and let us know how it goes.
Thank you!
Hi, Martin,
You’re correct, after performing this on the assets, the issue went away. We’d usually do these operations when encountering this, but we just weren’t sure if the cause wasn’t deeper into Live Link / Vantage anyway.
Thanks again,
