Detail this asset from Unity Asset Store: Original Link
This is a paid asset, but now you can download Lowpoly Substances Free.
Lowpoly Substances v1.4.1 (Latest version)
Lowpoly Substances v1.3
Lowpoly Substances is a set of shaders, materials and models that make stylized animations of fire and water (more substances to come). With Lowpoly Substances you can add stylish animated elements to your game without sacrificing performance.
Check out how it works:
Campfire demo (WebGL)
Customization demo (WebGL)
Features include:
• Performance: vertex shaders are very fast, this way of animation is much faster than particles
• Cross-platform: the effects work on all platforms, including mobile and WebGL
• Easy integration: drop one of the included prefabs and you’re done
• Customizable: animation shaders expose many parameters if you would like to change the animation
• Complete: the package includes different models of low-poly substances (and all additional models in demos)
• Flexible: the shaders and materials can be used on your own objects too
• Free updates
BTW, music in demo video is from Everloop, a non-linear soundtrack tool.
