SF Soft Shadow 2D

SFSS brings the highest performance and highest quality soft shadows to your 2D or 2.5D game. The algorithm is GPU accelerated and very mobile friendly.

NOTICE: SFSS works on Unity 2019.1 as of June 2019, but doesn't make enough money to justify further development. Future support will be minimal. The Lightweight Render Pipeline (LWRP), and HD Render Pipeline (HDRP) are not supported, and there is no plan to add it.
• Everything is optimized for mobile!
• Supports colored lighting with custom cookies
• Physically realistic penumbras
• Custom in-scene shadow editor
• Adjustable light radius/softness
• Supports atmospheric fog and bloom effects
• Adjustable dynamic range and HDR support.
• Works great in top-down or side scrolling games
• Add atmosphere and depth to caves, forests or even space
• Works great with isometric or perspective view games
No expensive image filters or pixel shaders are used to blur the shadows since it's neither mobile friendly or accurate. Instead, SFSS relies heavily on vertex shaders to compute accurate penumbras, umbras and antumbras in a single pass and a fraction of the performance cost. You get 2D shadows with better quality and performance on all platforms!
