• Client-only Fabric mod for 1.21.1 that locks your camera onto the endpoint of a selected player's F3+B blue line for smooth screenshots or POV mirroring. Tracking re-aligns every client tick and interpolates to avoid snapping.
• Use /track <player> to pick who to follow. Press V (configurable in Controls) to toggle tracking on/off. Optional helpers: /track status, /track distance <blocks>, /track smoothness <0-1>, /track interpolation on|off.
• The camera points from your view toward the target's eye position plus their look vector (default reach 8 blocks). Interpolation is enabled by default with a moderate smoothness factor to keep movement fluid.
• Safety: fully client-side, ignores missing/invalid targets, pauses when the target is invisible, in another dimension, or you disconnect, and avoids crashes by checking for nulls before acting.
• Notes: Settings are session-only (changeable via commands). Tracking rotates your local camera; expect your player model to face the target's focus direction while the feature is enabled.
