Default behaviour
ReplayCore detects staff who vanish with SuperVanish, PremiumVanish or EssentialsX vanish. By default vanished players are recorded, so staff reviews keep the complete picture. Set Vanished players to Exclude to keep them invisible in replays as they were in game: the replay then shows them despawning when they vanish and reappearing when they unvanish.
Any other vanish plugin that sets the de-facto standard 'vanished' player metadata key is detected identically.
Configuration
Open Configuration Studio, choose the relevant workspace, category or server scope, then set Recording > Vanished players to Exclude or Record. Record is the default. The field is marked restart-required, so restart the affected recorder after the published configuration is delivered.
What exclusion covers
Exclusion suppresses the vanished player's position, pose, vitals, equipment, and inventory records. Chat lines and commands they produce remain subject to the separate privacy settings. Vanish and unvanish transitions land on the exact tick they happened in game.
The check is a single metadata lookup per player per tick and allocates nothing for normal players, so it has no measurable performance cost. A misbehaving vanish plugin can never abort the capture: a metadata read that fails is treated as not vanished.
