A free campfire flames effect for pixel-art games: a simulation made in Blender (Mantaflow), its 24 .vdb files and its Blender scene, and the pixel-art sprite sheets Pixor rendered from them at 48 px, from every side. It loops without a jump.

Open the first .vdb file in Pixor and it plays the rest; the project in the zip has the colours and settings these sprites were rendered with. The .blend bakes the simulation again in Blender, to change it and make your own.

Good for fire, water and effects in fantasy and action games.

Use it in your game

  • Godot 4: godot/campfire-flames-vdb-clean-48.tres is a SpriteFrames resource with 8 animations (volume_South, volume_Southeast … volume_Southwest): drop it on an AnimatedSprite2D and play volume_South.
  • Aseprite: aseprite/campfire-flames-vdb-clean-48.aseprite has a tag for each of those, 160 frames in all, to touch up by hand; its .json sits next to it.
  • Unity, GameMaker and the rest: sprites/clean/campfire-flames-vdb-48px-8-sides.png has 8 rows of 48×48 px cells, one per action and side, South (front) first. A 4-side sheet and the 32 and 64 px sizes are next to it.
  • Posts and devlogs: the GIFs above, also in the zip’s gifs/ folder.
  • The simulation: simulation/vdb/ holds its 24 .vdb files; open the first in Pixor and it plays the rest, or open simulation/campfire-flames-vdb.pixor, the project these sprites came from, to change the look. simulation/campfire-flames-vdb.blend bakes it again in Blender.

The Style graph of this look: what each node makes, and its settings. Each name links to what the node does.

The other looks in the player (clean, retro, flat) are other Style graphs. With Pixor you can open this asset, change any node, and render your own.
