What causes Unity nameplates rendering through walls?

World-space nameplate canvases draw on top of everything with no depth test against the scene, so they remain visible even when the player is behind a wall.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Player Nameplates Showing Through Walls in Unity

Quick answer: Add a line-of-sight check from the camera to each tracked player and hide the nameplate when occluded, or render it with depth testing against scene geometry.

Nameplates that float through walls give away enemy positions and break immersion. In Unity the cause is UI that ignores scene depth. A per-frame occlusion raycast that hides blocked nameplates is the standard fix.

How to fix it

1. Raycast for line of sight

Each frame, cast from the camera toward each tracked player against your environment layer with Physics.Linecast; if it hits geometry first, hide that nameplate.

2. Throttle the checks

Occlusion-testing every nameplate every frame is wasteful at scale. Stagger checks across frames or only test players within view distance to keep the cost down.

3. Fade rather than pop

Instead of snapping nameplates on and off, fade their alpha when occlusion starts and stops so they do not flicker as a player edges past cover.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Unity error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
