Here is some high voxel simulated fire with smoke –
Full HD PNG 1920×1080 with Alpha
Frame rate – 25 fps duration
Duration: 500 Frames
This fire is simulated at about 30% real time so it can work for slightly slower footage or work well as a distant fire. If you increase the speed in your editing/VFX software it will also work for real time footage anywhere in your scene.
I hope this is useful to you and have fun making things burn.
