LCHD

HD visual tweaks for Lethal Company (v80+). LC runs on HDRP, so the mod uses HDRP-native APIs (HDAdditionalCameraData, Volume overrides) plus classic QualitySettings knobs. Everything is hot-reloadable via BepInEx config — edit the file while the game runs and the change applies within a few seconds without a restart.

What it does

Install

1. Install BepInEx 5 for Lethal Company.
2. Drop LCHD.dll into BepInEx/plugins/LCHD/.
3. Run the game once — BepInEx/config/com.lchd.cfg will be created.

Configuration

Edit BepInEx/config/com.lchd.cfg. Every setting hot-reloads.

[RayTracing]

GlobalIllumination = false         # RT GI (real indirect bounce light)

Ray Tracing requirements

To make [RayTracing] toggles actually do something:

1. DX12 rendering — launch the game with -force-d3d12 in Steam → right-click LC → Properties → Launch Options.
2. RTX-capable GPU — NVIDIA RTX 20xx/30xx/40xx, AMD RX 6000+/7000+, or Intel Arc A-series.
3. HDRP asset must have supportRayTracing enabled. Vanilla LC ships with this off — you'd need to edit Lethal Company_Data/StreamingAssets/aa/... or use a separate mod that flips that flag.

If any of these is missing, the toggles are silent no-ops. On startup the mod logs:

RayTracing capability: SystemInfo.supportsRayTracing=true, GraphicsDevice=Direct3D12. OK.

If you see supportsRayTracing=false, RT won't work no matter what you set in config.

Presets

Crisp HD:

RetroOverride.Enabled = true
RetroOverride.Scale = 1.0
HDRPMode = 2                       # TAA
LodBias = 2.0
PostProcessing.Vignette = false
PostProcessing.FilmGrain = false

Toaster (low-end):

RetroOverride.Enabled = true
RetroOverride.Scale = 0.75
HDRPMode = 1                       # FXAA
MipmapLimit = 2
ShadowDistance = 30
LodBias = 0.8
PixelLightCount = 1

Cinematic (max quality):

RetroOverride.Enabled = true
RetroOverride.Scale = 1.5
HDRPMode = 2                       # TAA
ShadowDistance = 120
ShadowResolution = 3
LodBias = 2.5
PixelLightCount = 8

Notes & caveats

• HDRP retro override resizes the player camera's render target each second. If LC's UI quad caches the texture pointer, output should still update because we resize in place rather than swapping the asset.
• Head-bob suppression is reflective — finds fields named *bob* on PlayerControllerB and zeroes them in LateUpdate postfix. Check log for HeadBob: matched N field(s). If N=0, tell me the field names and I'll patch directly.
• Volume overrides affect every active HDRP Volume in the scene. If a moon has its own override volume, it'll be touched too.
• All settings are client-local.
