Anti-aliasing ​

Anti-aliasing smooths out jagged edges (also called "stair-stepping" or "aliasing") on your 3D model and scene, producing cleaner, more photorealistic renders. In iJewel Playground, anti-aliasing is split into three independent sections — Progressive, Temporal AA, and Velocity Buffer (TAA) — each designed for a different rendering scenario.

Where to Find It ​

This section is located on the right panel, accessible via the Anti-aliasingAnti-aliasing tab.

How the Three Sections Work Together ​

Each anti-aliasing method targets a specific use case:

Progressive
Multi-frame accumulation for still images. The renderer takes multiple samples over time and averages them to eliminate aliasing. Best for final image exports where you can wait a few seconds for the render to converge. Read more →
Temporal AA
Real-time anti-aliasing for interactive use and animations. Blends the current frame with previous frames to smooth edges while you rotate, zoom, or play animations. Keeps the viewport clean without the wait time of Progressive. Read more →
Velocity Buffer (TAA)
Motion-aware temporal anti-aliasing that uses per-pixel velocity data to reduce ghosting artifacts when objects or the camera move. An advanced complement to Temporal AA for scenes with animation. Read more →

Quick Guide: Which Setting to Use ​

For Still Image Exports

Increase the Progressive → Frame count to 16, 32, or higher. The more frames, the smoother the result — but the longer the render takes. This is the single most impactful setting for image quality.

For Real-Time Viewport & Video Recording

Enable Temporal AA and keep the default Feedback values (0.88 / 0.97). This gives you smooth edges in the viewport and during video export without a long convergence wait. If you see ghosting on moving objects, enable Velocity Buffer (TAA).

For Fast Previews

Lower the Progressive → Frame count to 4 or 8 for quicker convergence. You can also disable Progressive entirely and rely on Temporal AA alone for a responsive viewport.

Performance Note

Higher Progressive frame counts significantly increase export time — especially for video. If your video export takes 10+ minutes, try reducing Progressive frames to 4–8 and relying on Temporal AA instead. See the FAQ on video export speed for more tips.
