About OdinsUndercroft
From ThunderstoreA `Basement` alternative, a more castle-like private basement. Now with Deco and BuildKit pieces! Fixed compatibility for ComfyGizmo Mod!
OdinsUndercroft
by OdinPlus
🏛️ A private basement befitting a Viking lord, rather than some dirty hole in the ground.
About:
Build the entrance anywhere you like and step down into a fully enclosed stone undercroft that's yours to furnish.
Features:
- Buildable Dungeon/Undercroft with a full set of matching stone, iron, and bone decor pieces (found in the Undercroft tab of your Hammer).
- Three Interior Areas — a grand hall and two side rooms. Each can be toggled off in the config for a more compact build.
- Protection: Accidental demolition is prevented while anything is still built inside.
- Smart Placement: Range check stops you from placing an Undercroft too close to an existing one.
- Performance Optimized: Triggers, colliders, and water volumes that serve no purpose underground are culled.
Configuration:
Settings live in BepInEx/config/gravebear.odinsundercroft.cfg and can be edited while the game is running — changes apply immediately.
