WispTorchHeeler

Tiered Mistlands wisp torches and demister lamps with expanded mist clearance, interactive torch painting, and multiplayer color synchronization.

[!NOTE] Client & Server Compatibility: This mod is safe to install on local clients and runs cleanly on dedicated servers with zero desyncs and server-enforced policies. For custom pieces in multiplayer, both client and server require the mod.

The Problem

In vanilla Valheim, clearing the thick mist of the Mistlands requires placing dozens of small, fragile native wisp torches in close proximity. This creates:

• Severe Visual Clutter & Construction Fatigue: Expansive Mistlands bases, farms, and transit paths quickly devolve into chaotic thickets of sticks.
• Performance Overhead: Dozens of overlapping particle system force fields, dynamic point lights, and particle emitters ticking simultaneously cause noticeable framerate drops.
• Rigid Aesthetics: Builders are locked into a single fixed cyan/white color palette that cannot be customized to fit different build themes, architectural styles, or interior moods.
• Fragility: Native torches possess only 100 HP, breaking easily from collateral combat damage, seeker attacks, or stray dvergr fire.

The Solution

WispTorchHeeler introduces four tiered, late-game Mistlands lighting installations with progressively larger mist-clearance radii alongside an interactive, crosshair-driven "Torch Painter" system and multiplayer color synchronization via Valheim's native Zero Data Object (ZDO) architecture:

• Tiered Mist Clearance: Four distinct lighting fixtures ranging from reinforced large torches to colossal dwarven monuments, clearing up to 3.0× the fog radius (9× coverage area) to drastically reduce piece density and visual clutter.
• Interactive Torch Painter: Aim at any placed torch or lamp and press P to instantly paint its light and particle effects with your chosen color, or LeftShift + P to reset it.
• Auto-Paint on Placement: Newly placed torches and lamps can automatically inherit your active painter color the instant you build them.
• Multiplayer & Server-Synchronized: Stamped directly into each piece's ZDO at creation with zero desync. Unpainted pieces can inherit client-chosen defaults or server-enforced color themes, with ward-protection permissions and admin overrides.
• Zero Asset Bundles: Cloned cleanly from native Valheim prefabs at runtime using Jötunn, ensuring instant load times and lightweight installation.

• Auto-Paint on Placement: Enable AutoPaintOnPlacement in config to automatically paint newly placed torches and lamps with your active color upon hammer placement.
• Paint in World: Aim your crosshair at any wisp torch or lamp within reach and press P (configurable via PaintTorchHotkey). An on-screen prompt displays when in range.
• Reset Piece: Aim at a painted piece and press LeftShift + P (configurable via ResetTorchHotkey) to revert to default color.
• Ward Protection & Security: Non-permitted players cannot paint pieces inside active wards unless permitted by server policy (AllowPaintingInProtectedWards) or admin status (AdminBypassesWardCheck).
• Multiplayer Synchronization: Painted colors synchronize across all clients via ZDO and persistent world storage without requiring external asset bundles.
• Visual Mist Boundary: Enable ShowMistSuppressionRadius in debug config to project a real-time ground ring showing the active mist suppression radius of all wisp pieces.

Configuration

Settings can be customized directly in-game using the BepInEx Configuration Manager (F1) or by editing BepInEx/config/dreamwraith.WispTorchHeeler.cfg:

[1.1.0] - 2026-09-29

Added

• PlayerBase Support on Lamps: Added PlayerBase components and trigger colliders to all custom Dvergr lamps on the character_trigger layer so they suppress enemy spawns and count toward player base structure recognition.
  • note: I managed to release custom lamps that didn't actually count as base structures. You can now build them without enemies spawning all up in your base.
• Dynamic Spawn Suppression Slider: Added the PlayerBaseMistRadiusBonus server-synced config setting, allowing spawn suppression to scale from the native 20m base up to matching the full mist clearance radius.
  • note: If you want your safe zone to match your clear view, now it can. If you leave it at 0, it stays at the native 20m default so the game balance still balances... mostly.
• Normalized Native Baselines: Standardized internal base values across all tiers to 24m mist clearance, 10m light range, 1.0 light intensity, and 20m PlayerBase suppression radius.
  • note: Each fixture originally inherited whatever numbers Iron Gate gave its donor prefab. I should have looked way closer at the default values on the prefabs I was using, as this made the configuration confusing as all hell. Now everything is normalized on the same base values, so the math can math much mathier.

Changed

• Linear Tier Scaling Toward Grand Demister: Re-adjusted default mist clearance multipliers to scale in clean +0.75x (+18m) steps up to the 90m Grand Demister default:
  • Tier 1 (Large Torch): 1.50x (36m)
  • Tier 2 (Small Lamp): 2.25x (54m)
  • Tier 3 (Large Lamp): 3.00x (72m)
  • Tier 4 (Grand Lamp): 3.75x (90m)
  • note: The earlier progression was uneven because I was eyeballing multiplier jumps. It now steps by an even 18 meters per tier.
• Normalized Light Scaling: Light ranges and intensities now scale off common 10m and 1.0 baselines across all tiers.
  • note: The large demister prop had a native 20m light range that doubled on top of my multipliers and created a miniature sun. It now scales from 10m like everything else.
• Clean Config Descriptions: Rewrote config descriptions to state final numbers relative to stated baselines instead of referencing internal prefab mechanics.
  • note: All my homies reading config files didn't have a clue what I was rambling about. It now just tells you what baseline number you are multiplying.
• Terminology Cleanup: Replaced occurrences of "vanilla" with "native" across code comments and documentation.
  • note: I know the community loves the term vanilla, but I differ, and prefer native. Nonetheless... I went against my own principles in a few places originally, and have now cleaned those up.

Fixed

• Crop Growth Blocked by Lamps (Commit 39add34): Fixed piece collider setup in WispPieceManager to skip trigger colliders when assigning objects to the piece layer. Triggers remain on character_trigger (Layer 14).
  • note: Yes, my torches were accidentally suffocating your cheesy poofs. Unity triggers placed on physical layers make the crop spacing check think there's a solid rock in the dirt (or above the cheesy poofs knob). This was just me using a blunt instrument to solve a collider problem for the build hammer. No more!
