Fire Shaders

Henlo all! 🔥 Today I am releasing some of my old studies as free, open-source and permissible shaders for you all to use! There are a lot of features as well as prefabs for your convenience. These shaders mimic both stylized, anime/toon fire in Unity and a realistic flame effect in Unity (as well as the ash particles).

🍱 What's in it?

• Two fire/flame shaders with two variants each (Real Fire, Toon Fire, Real Fire Stencil, and Toon Fire Stencil)
• Light-weight and optimized shaders and setups (single pass, no grabpasses, one plane or particle, no keywords).
• Two prefabs with materials, ashes, and particle systems set up (one for toon and one for real)
• A permissive license and simple README with instructions, as well as texture maps to use
• Perfect for a number of uses in games, worlds, and avatars – anime fireball projectiles, candles, torches, furnaces, dungeons, campfires, explosions, and more!

🕯️What all can it do?

• Customizable low-temperature and high-temperature colours
• Precise and easy distortion settings (you can see them in the preview)
• Control over brightness and alpha values, with max limits (for making it glow in bloom!)
• Uses texture maps instead of real-time noise for performance benefits
• Stencil variations allow the flames to be hidden around objects, such as a candle, to prevent over-rendering or clipping
• Toon: supports controlling the shape of the flame with a slider as well as the "toon" stylization strength
• Real: supports an optional "dissolve" map that adds to the distortion of the flame, as well as a mask for the shape of the flame

🧐What is the license?

• You can redistribute it in transformative works both personally and commercially (with attribution).
• You may edit it as a long as you make note of the changes
• You may not simply redistribute the package or code, or take credit for it.

If you have questions, feel free to reach out to me through Discord or Email (both of which can be found on my website here)! Thank you for reading and have a great day 🌈
