Simple, real-time cursed energy experiment/demo based on the flame effects from jujutsu kaisen using a mix of shader/geometry and compositor nodes (real-time compositor). There aren't a lot options in this but you can navigate to geometry nodes/compositor tabs to change outline thickness/color. Blender 3.5+ is required as this uses the new real-time compositor, but for older versions you should still be able to manually render to see the effects. License: CC0
