Q: What is the Black Smoke bug?

The Black Smoke bug is a visual glitch in 7 Days to Die where thick black smoke appears unexpectedly and lingers on screen. It may happen during normal gameplay, combat, or high-activity moments, but it is not consistently tied to one specific action.

Q: What triggers it?

There is no confirmed single trigger. Some players report it happening more often during heavy zombie activity or intense combat, but it has not been definitively linked to gunfire, hordes, or a specific mechanic. The cause has not been officially pinpointed.

Q: Is this caused by the Asylum Overhaul mod?

No. This is a vanilla engine issue. It occurs in the base game and is not caused by the Asylum mod.

Q: Does relogging fix it?

Relogging does not reliably fix the issue. The smoke may temporarily clear but can return later.

Q: Can updating drivers fix it?

Some players report that updating GPU drivers has reduced or stopped the issue for them. However, this is not a confirmed universal fix. In certain cases, outdated graphics drivers may contribute to particle rendering problems, so updating drivers is recommended as a troubleshooting step.

Q: Is there a confirmed permanent fix?

At the time of writing, there is no officially confirmed permanent fix from the developers. Because this is a vanilla engine-side issue, only the core 7 Days to Die developers can resolve it in a future patch.
