As a ray-tracing renderer, Vantage can produce flickering or splotchy render results when using High Quality Render for animations.
Flickering in animation is most commonly caused by:
- Not enough Samples per pixel. Interior projects may need a lot more samples than exterior ones. Using values between 1000 and 2000 can result in flicker/splotchy-free rendering results.
UI Path: Tools > High Quality Render
- The default Light Cache Sample limit might be insufficient. Similar to the Samples per pixel, interior projects may need a lot more Light Cache samples than exterior ones. Using values around 1000 or more can help to get flicker/splotchy-free rendering results.
UI Path: File > Advanced Scene Settings
- Outdated Nvidia Drivers. Such drivers can introduce artifacts when denoising the final image. It is best to use the recommended NVIDIA driver version shown here.
Additional options for troubleshooting:
- Try rendering a few frames without a denoiser.
- Turn off the Enable dynamic textures option (in Render tab > Advanced).
- Increase the Light Cache’s Retrace threshold to 3.
Use the Reduce flickering option (in Tools menu > High Quality Render).
Archive and send the files to Chaos Support if any additional help is needed.
Files required for additional troubleshooting by Chaos Support:
- Vantage project file, and .vrscene file associated with the Vantage project file;
- Project file from the 3D platform used to initiate the Live-Link connection or to export the .vrscene file.
