Works with your sword

1. Set any object as the modifier's Sword input: katana, axe, spear or your own model.
2. Add a vertex group named Blade along the cutting edge, from guard to tip.
3. Animate the swing (or parent the weapon to a hand bone). The trail follows.

Controls on the modifier

• Trail: on/off, lifetime (MaxAge), resolution, curve type, material.
• Sparks: count, lifetime, velocity, rotation mode, scale, material.
• Particle layers 1 and 2 (smoke, leaves, bats, pixels): count, lifetime, velocity, rotation mode (align to velocity / face camera), scale, material.
• Swap the materials to make your own style.

How to use

1. Open the .blend and select a Blade_FX object.
2. Replace the sword or keep the included one, and animate it.
3. Before rendering, bake the simulation: Physics properties > Simulation Nodes > Bake All. For a viewport preview, just play from frame 1.
4. Render in Eevee.

Requirements
