  • Denoiser Restarting Large Scenes Causing Blurred Results

    Using the latest version on Max 2022 with last version of ForestPack Pro.
    Extremely large scene processing on one 3090.
    Lots of forespack items off in the distance.
    Trying to render out 4,000 x 2,229 images.
    Takes up over 19 GB of memory on the card.
    Using Nvidia AI although Combo isn't any better.
    Nvidia Studio Drivers 522.30.

    Noticing that initially when the scene is sent live to Vantage, it renders out fine.
    But if I switch the cameras or make adjustments, Vantage starts to process the new camera angles, appears to finish, then restarts to reprocess the denoiser again. It keeps it on a loop eventually making it barely usable. Then if I save out the images, sometimes I get a sharp image (trees are sharp) but other times (most of the time) I get unlucky and it saves out a very blurred image of the trees.

    Doesn't seem to make any difference if opacity is selected or not.

    It appears to be some sort of memory issue or timing triggering a restart of the denoiser passes instead of finalizing.

    If I keep the Vantage viewport small and use HQ rendering (denoiser set only to final pass), I can render out more images without blur, but eventually I need to start all over again.
    This would indicate to me that it's some sort of memory issue perhaps related to the AI denoiser not resetting properly although I don't see it in the lower right hand corner of Vantage increasing.

    Probably easier for me to show you a small preview. Larger image looks far worse. Left is the the blurred version and right is the initial version.

      Why do you assume it's the denoiser that's causing this ?
      The denoiser doesn't need to restart the sampling process in order to apply itself - it works as a post-process.

      Are you running the live link when this happens ? Maybe there is some code on the 3dsMax side (a script?)
      that keeps changing the scene in some way, which causes Vantage to restart the sampling process.

      A screen-recording that shows the issue or a .max scene that reproduces it would be very helpful.

      Which Vantage and V-Ray for 3dsMax versions are you using ?
