HI,
In postprocess materials, when i use the scene base color (for lighting) texture with Temporal AA, i got lot of flickering. Is there something that I could do to fix it ?
Many Thanks.
Postprocess flickering is a visual artifact that occurs in graphics rendering, often due to post-processing effects like anti-aliasing, bloom, or motion blur. It can be caused by inconsistent frame rates, shader precision issues, or temporal filtering techniques. To fix flickering, developers can adjust settings such as temporal anti-aliasing (TAA) stability, increase sample rates, or fine-tune motion vectors. In gaming and CGI, reducing flickering enhances visual clarity and immersion. Using higher bit-depth textures, optimizing depth buffers, and balancing post-processing effects can help minimize unwanted flickering in rendered scenes.
Post-process flickering refers to unwanted fluctuations in visual effects applied during the post-processing stage of image or video rendering. This issue can manifest as inconsistent lighting, color shifts, or other visual artifacts, often resulting from improper settings or limitations within the rendering engine. For instance, in Unity’s Universal Render Pipeline (URP), the bloom effect may flicker due to its default half-resolution setting; adjusting it to full resolution can mitigate this problem.
Similarly, in Unreal Engine 5, flickering shadows have been observed when using global illumination settings, particularly with small objects like grass; switching the Skylight actor mode to Stationary has been suggested as a potential solution.

Addressing post-process flickering typically involves fine-tuning rendering parameters, updating software, or modifying specific effect settings to achieve stable and consistent visuals.
