I’m rendering an interior space with Vantage and there are some strange artifacts appearing around my ceiling lights, they are plane vray lights. Take a look at this animation and tell me what you think is causing this and how I can fix it, please!
What Vantage build are you using ?
What’s your GPU and driver version ?
Greetings,
Vladimir Nedev
I’ve tried build 2.2.3 and 2.3 and it shows up in both of them. I have a Geforce RTX 3080 using this driver version 31.0.15.5123.
Is motion blur enabled? Our motion blur is a post-processing pass and can sometimes produce similar streaks (it was intended for interactive mode but we ended up allowing it for final renders due to the lack of raytraced blur).
Maybe a fix would be to use the the rect lights to illuminate the space, but make them invisible. Add a self-illuminated texture and bump the intensity up. In Vantage turn on Bloom and set it enough to see some bloom along the edges of your fixture.
I updated Vantage to the newest version and installed the most current Nvidai drivers, but the streaks are still there. I tried hiding the lights and the streaks did disappear from the lights but the snorkels hanging from the ceiling started producing them, this time they were coming from the metal material on them. I disabled motion blur in 3D Studio and turned it off in Vantage saving that configuration as default, but it didn’t work, and motion blur was still happening. I also disabled caustics in Vantage thinking that was the cause, but it was still happening, I’m not 100% sure that the setting changes stuck in Vantage though. I’ve been using Vantage since it came out years ago, this is the first time I’ve seen this problem, please help!!!
motion blur was still happening
This is very strange. I think we will need some screenshots or video…
The video is posted above.
I meant we need to see your steps in the UI because I can’t imagine how you can disable motion blur and it would still render motion blur.
Ok the problem is being caused by motion blur, any idea how to fix this?
This post-processed motion blur was added for interactive rendering in the earliest versions of Lavina. At some point we allowed it for offline renders because of the lack of raytraced blur, but its quality is often not good enough for final renders. I think your only alternative is to render with no blur.
Video is inaccessible.
Are you using Optix + “reduce flickering”? You have many lights - try using reservoir resampling (“spatial importance” is probably better kept disabled). Also try more LC samples if those were low to begin with.
I was able to log in with a google account to watch it. So the flickering on the ceiling seems to be from “regular” sampling noise. I noticed some weird artifacts around vertical edges (e.g. around 0:10 and 0:38 ) - those are weird and I’m not sure what is causing them.
Another thing to try is to enable Preferences->Render defaults->Optix Legacy mode.
You are using driver 551.23 and a single 3080, right?
I’m using the most current version of the Nvidia driver for a 3080 (31.0.15.5212).

Increase light cache samples to 2000? In my experience spatial importance often increases flickering - have you compared this setting without touching the others? Maybe you also need a bit more camera samples as well.
For interior animations I typically use between 500 to 800 samples and get clean results. I know that it will take longer to render. Another thing I typically change is the noise threshold number. Between .003 and .005. I checked shading graph for glossy/gi also.
Which samples are you talking about…Light Cache?
Where it says Quality in the render dialogue window.
So this a good place to ask. Since the motion blur is a post process per frame, does it: 1. Add to render times if we have it checked 2. Does it add to the realism of the final output? If not, then why use it?
