What It Does
Nice Curves generates rounded corners on arbitrary shape paths using null-controlled vertices. Unlike After Effects’ built-in Round Corners effect, which often produces unequal or sharp results, this plugin calculates corners with consistent roundedness across all vertices.
The tool creates expression-driven masks that remain nondestructive, letting you adjust curve properties without permanently altering your original paths.
Key Features
Equal roundedness calculation. The plugin ensures consistent curve distribution across all corners, avoiding the visual inconsistencies common with the standard Round Corners effect.
Per-vertex control. Adjust curve depth and roundedness for individual vertices or apply changes globally across the entire path.
Unlimited control points. Add as many null controllers as needed to build complex curved shapes. Create multiple independent paths within a single composition.
Expression-based workflow. All curves are driven by expressions, making them easy to fine-tune and animate without destructive edits.
Who It’s For
Motion designers working with shape layers who need precise control over rounded corners. Particularly useful for isometric design, graphic elements, and any project requiring smooth, consistent curves that can be animated over time.
Pricing
Nice Curves uses a pay-what-you-want model. Individual users can contribute any amount (suggested minimum $19.95). Business and team licenses require the full suggested price for valid licensing.
Compatible with After Effects CC2018 through 2024.
