What causes jagged edges in renders, and how can they be reduced?

Asked on Dec 07, 2025

Answer

Jagged edges in renders, often referred to as aliasing, occur when the resolution is too low to capture smooth transitions between edges, leading to a stair-step appearance. Reducing jagged edges typically involves using anti-aliasing techniques to smooth out these transitions and improve visual quality.

Example Technique:

Step 1 – Increase the render resolution to capture more detail.
Step 2 – Enable anti-aliasing settings in your rendering software, such as MSAA or FXAA.
Step 3 – Adjust sampling rates to ensure smoother edge transitions and refine the final output.

Additional Comment:

Higher resolutions provide more pixels to define edges, reducing aliasing.
Anti-aliasing methods like MSAA (Multi-Sample Anti-Aliasing) and FXAA (Fast Approximate Anti-Aliasing) help smooth edges.
Balancing quality and performance is key, as higher settings can increase render times.
