Reduce Flickering on Thin Objects Like Fences and Leaves

Understanding TAA for Thin Geometry

Temporal Anti-Aliasing (TAA) works by blending information from multiple frames to smooth out movement artifacts. Thin objects like fences, leaves, and vines are particularly prone to flickering because they have sharp edges that change appearance frame-to-frame.

How to Minimize Flickering

1. Enable TAA in your shader settings — Look for the TAA toggle in your shader configuration menu. This is the primary tool for reducing flicker on thin geometry.

2. Adjust your camera movement speed — Slower, smoother camera pans reduce the temporal difference between frames, making TAA more effective. Avoid rapid head turns when viewing foliage.

3. Position yourself strategically — View thin objects at angles rather than head-on when possible. This reduces the visual impact of any remaining shimmer.

4. Combine with FXAA — Enable FXAA alongside TAA for additional edge smoothing. FXAA handles spatial aliasing while TAA manages temporal artifacts.

Note

Some flickering may persist on extremely thin textures or at certain angles—this is a limitation of real-time anti-aliasing techniques. If flickering is severe, verify that both TAA and FXAA are properly enabled in your shader options.
