What causes effects not showing in a build?

The effect's shader or material was stripped from the build because nothing referenced it directly, or the effect asset was not included, so it renders nothing in the shipped game.

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 Particles or Effects Not Showing in a Build

Quick answer: Ensure effect shaders are included (always-included list or a scene reference) so they are not stripped, confirm the effect assets ship, and test effects in a development build.

Effects that work in the editor but vanish in the build are usually stripped shaders or unincluded assets. Ensuring they ship fixes it. Here is how.

How to fix it

1. Keep effect shaders from being stripped

Shaders used only by runtime-spawned effects can be stripped because the build does not see them referenced. Add them to the always-included shader list or reference them from a scene so they ship.

2. Confirm the effect assets are included

Effects loaded dynamically must be in a location the build includes (a resources folder or an asset bundle). An effect not packaged simply does not exist at runtime.

3. Test in a development build

Effects missing only in builds need a development build with logging to confirm whether the shader, the material, or the asset is the missing piece, rather than guessing.

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 your game 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.

Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
