Hot Air Refraction is a set of shaders designed to simulate warm air around objects, such as fire, asphalt, exhausts, and chimneys. This package is essential for creating visually appealing and immersive environments. With its ease of use, fast performance, and low VRAM usage, it's perfect for mobile and other platforms. The package includes different shaders and presets for customization, and its modular shader graph code makes it easy to expand and modify. Supported Unity versions include 2020.3 LTS, 2021.3 LTS, 2022.3 LTS, and Unity 6. Tested on various platforms, including Android, iOS, WebGL, Windows, MacOS, Linux, VR, and AR.
The package includes three shaders:
HeatDistortionNoMask: A simple and performant shader without edge masking, with hard edges where the 3D model ends.
HeatDistortionPlane: Similar to NoMask, but with masking made for planes and quads, with a drop-off of the distortion effect around the edges and a HeightDropDown variable to adjust the distortion height.
HeatDistortionSpherical: Using Fresnel for masking, this shader looks the best and requires smooth edges, like on a capsule.
All shaders are designed to work on all platforms and are optimized for fast performance.
