Hi! I’m rendering a large animation on Vantage but on this one, I’m getting a lot of noise/flickering on the video. Still images look just fine, please check the video and help me with any ideas. I have already tried increasing the samples and adjusting the ray termination values.
Thanks!

I have exported this as a live link and full scene and the issue is the same.
You posted in the other thread that you solved your issue by increasing camera samples to 400 and light samples to 16. Correct? I was going to suggest disabling “dynamic textures”, “ray termination” and maybe light cache to see if that helps and if it didn’t, then just use more samples. It seems it just needed more samples to reduce the noise sufficiently (the flickering occurs because the denoiser is getting too much noise).
Where do I disable dynamic textures?
something weird happened when I disabled ray termination, when I did it and went to the export dialogue I was getting a notification that I didn’t had enough memory to export. And this was with regular settings.
BTW, the first bed that you see in this video was giving me problems in the animation even with the upgraded settings, might it be something with the model?

It could be an issue with the model, or it could be a problem with the Vantage bump mapping when combined with dynamic textures.
You can try disabling bump mapping on the bed material.
This might fix the problem without having to disable dynamic textures (which leads to increased GPU memory consumption).

It’s most likely a coincidence, unless it’s something you can reliably reproduce ?
I don’t think I’ve seen this message, can you take a screen-shot if it appears again ?

I left rendering overnight night and it crashed about 3 hrs ago.
In such cases, the Vantage debug log might help us.
However, you need to make a copy of it before starting Vantage again, as it will get overwritten.

Turning “dynamic textures” on or off doesn’t have an effect on the sampling noise, so you can enable it to save on memory.

I suggested disabling dynamic textures mainly because of that flickering bed, to see if it would stabilize.
I believe you can still render even though the memory estimation is in red, specifically when it’s only 1GB above budget. The OS usually manages to handle this by swapping memory to CPU RAM.
Thanks! that made the trick, I’m rendering 90 frames @ 4k, 250 samples, and “dynamic textures” on, it will take about 2.5hrs, might cut it short just to see how it looks.
But thanks a lot for all the help, there should be an online tutorial explaining the management of memory.
Not sure, you might have to increase the number of AA samples instead.
How many light tree samples did you use ?
Some of this jittering could be caused by the light cache too, but it’s hard to tell.

I have it at one light tree samples, should I increase it? is 500 AA samples too much?
The noise in the lantern in front of the house can definitely be improved by more light tree samples.
It’s hard to say what the ideal combination is.
500 AA samples can be too much or too little depending on what you have in the scene.
If you have lots of lights, using more light tree samples might be better than increasing AA samples.
You can try different setups by rendering a few frames until you are happy with the result.

Well, you could
- bump up the AA samples even further than 300 OR
- try disabling the light cache from File->Advanced settings, as it could be causing flickering in some cases
(this could also lead to more flickering however).

Try disabling “dynamic textures” in Render->Advanced. It looks like the floor texture level of detail change causes the change in reflections there.
I wasn’t able to see the edge flickering though.
Nikola is right, it’s most likely the dynamic textures in combination with bump mapping that’s causing this.
Can you send us the scene or at least the floor with its material and textures ?

HI, here is the link to the scene and texture. The floor is created using the floor generator.

The first link doesn’t seem to work, it says the file is either missing or I don’t have access.

oh, weird, here is an updated link, 1.6 GB:
Thanks, but in that scene the floor has a material called “Piso COncreto” with a bump texture called “d8684792_Bump_4k_raw.tx”.
I don’t think that’s the correct one ?
Can you please save the floor in its own scene and make sure it has the correct material and also that the OneDrive link includes all required textures ?

Hi, the object is called “000 WOOD FLOOR”. Here is the correct link:
