SlashForge - Combat Trail Creator

SlashForge is a procedural sword slash creator for Unity that turns every part of a slash trail into an accessible and deeply customizable workflow using a layered approach, essentially a visual editor built specifically for slash effects.

Create unique sword trails and melee slash effects by controlling their shape, movement, textures, colors, timing, distortion, and more; all through easy custom editor tools.

43 production-ready trails that work out of the box are included. Simply attach one to your weapon and start using it. (It doesn't need a character with an animator, would even work in an empty game object)

It can be used for any type of melee combat (or any field where procedural mesh trail effects and sword trails might be applicable)

• VertexColor.B: Trail Endings (for smoothening where they end)

For VFX artists:

Gain more control while working significantly faster. SlashForge handles the technical burden of procedural mesh generation, trail sampling, lifetime data, UV creation, and batching so you can focus on artistic direction rather than rebuilding the underlying systems and shader math.

For developers and artists without VFX experience:

SlashForge makes advanced artistic controls accessible through an intuitive editor workflow. The documentation also explains the visual principles behind creating effective sword trails, giving you the best possible chance of producing effects that fit your game.

Or simply use one of the production-ready trails included in the package. Your combat can have polished slash effects and have your taste without requiring you to become a VFX artist first.
