Configuration

The config file has a list of object ids that are ignored by the smoke. Check here for object ids.

By default following structures let the smoke pass:

  • Cage Floor 1x1
  • Cage Floor 2x2
  • Cage Wall 1x1
  • Cage Wall 2x2
  • Carved Darkwood divider
  • Iron gate
  • Wood ladder
  • Wood stair

There are also settings to change smoke properties:

  • Collider size multiplier (default 1): Affects only the collider size.
  • Fade time (default 2): Seconds to disappear after max amount or max duration.
  • Force (default 2): Multiplies acceleration (how quickly target velocity is reached).
  • Max amount (default 100): Maximum amount of smoke.
  • Max duration (default 60): Seconds until starting to fade.
  • Random horizontal velocity (default 0.15): Random horizontal velocity.
  • Smoke size multiplier (default 1): Affects both visual and the collider size.
  • Vertical velocity (default 0.75): Maximum vertical velocity.

Other setings:

  • Required space (default 0.5): Clear space needed above fireplaces (meters). 0 disables the check.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Dependencies

Install these first, or the mod will not work:
