SwfMesh

A native SWF player for Unity and Godot.

SwfMesh faithfully renders SWF vector graphics as tessellated native meshes and plays timeline animation directly in your engine, in 3D or in 2D.

Make a SWF. Import it. Drop it into scene. That's it.

No asset piles. No intermediate formats. No conversion pipeline. Just SWF.

Get SwfMesh#

SwfMesh is a one-time per engine paid product.

SwfMesh is in closed beta and is not yet on sale. Access is invite-only for now and arranged by email.

→ Email hello@swfmesh.com for beta access. Tell us which engine you use and roughly what you are building - it helps us prioritise.

Nintendo Switch binaries are distributed separately, under NDA - see Platforms.

Why SwfMesh?#

Most SWF tools don't actually play your SWF. They force you to convert it into some splintered bullshit. You're left juggling garbage.

SwfMesh respects you and your swf.

Inspired by Scaleform and Ruffle, your SWF remains the source of truth. SwfMesh parses and plays it directly, generating the geometry it needs at runtime.

That means you can keep authoring in the tools you already know while using your SWF content as a native part of your game.

Beta access - hello@swfmesh.com. SwfMesh is in closed beta; tell us which engine you use and what you are building.

Support and bug reports - hello@swfmesh.com. Include your engine and SwfMesh version, and attach a .swf that reproduces the problem where you can. SWF files vary enormously, and a bug in one is usually about the specific tags that file uses - a description of the content works when you cannot share the file.

Feature and platform requests - hello@swfmesh.com. If a build target you need is not listed above, ask; see Platforms.
