[Product Description]

2D Rain & Snow - Layered & Occluded "Specifically designed for game development to ensure seamless integration."

This asset provides 2D and Pixel Art style rain and snow effects for Unreal Engine projects. Built as a post-process material, it offers more depth and environmental interaction than simple overlays. ( Post Process Material )

* Key Highlights

  • Multi-Layer Support: Supports 3 independent layers (Foreground, Midground, Background) to create a natural sense of space and parallax.

  • Smart Occlusion: Prevents rain and snow from appearing indoors or under shelters using Custom Depth and Stencil masking.

  • Easy Customization: Over 20 parameters, including color, opacity, density, and wave motion, allow for easy adjustments to match your project's style.

  • Efficient Performance: Designed as a post-process effect for effective resource management during gameplay.
