Melting Cut effect

Hey everyone!

I’m trying to recreate an effect similar to the one in the scene below (from The Phantom Menace) — where the lightsaber melts through the blast door and the metal glows and deforms around the blade.

I’ve tried a bunch of things like:

  • Emissive planes with animated masks and WPO
  • Decals with translucent or additive blend
  • Material parameter animations using timelines
  • Spawned meshes
    But nothing really gives the right feeling yet.

How would you go about achieving something like this? The screenshot is just the best visual reference I could find.

It’s not for a lightsaber effect.

Thank you guys!

Appreciate any ideas or suggestions!
