Summary
Starting from Unreal Engine 5.8, the stereo rendering in nDisplay is showing heavy rendering artifacts (mainly blur and jitter), especially when using any kind of temporal anti-aliasing such as TAA or TSR.
This happens for both stereoscopic rendering (L/R, T/B,..) or forced monoscopic rendering with a stereo offset (two Viewpoint Cameras with stereo offset applied). It occurs on multiple Windows 11 PCs in the nDisplay Template without changing any default settings.
Applying a manual offset by simply offsetting the Viewpoint does not lead to any artifacts.
What Type of Bug are you experiencing?
Virtual Production
Steps to Reproduce
- Create a Project based on the nDisplay Template
- Modify the NDC_Basic DCRA in the scene such that the
DefaultViewPointuses any Stereo Offset (Left/Right) - Launch Switchboard, add the NDC_Basic nDisplay device and observe the artifacts.
- Try different Anti-Aliasing methods to see different issues
Expected Result
No rendering artifacts should be visibile, the rendered image should be identical to e.g. a manual offset.
Observed Result
Severe rendering artifacts visible with TSR and TAA.
Slight rendering artifacts (especially in text rendering) for FXAA or no AA
