Hardcore Fluid Overhaul
Changing Minecraft fluid handling to be semi-realistic and push for more creative usages.
About this Mod
A simple mod that changes how the player interacts with water and lava in the world.
💧 Water
Water source blocks cannot be placed.
Instead, water dissipates shortly after being placed.This encourages building water channels and choosing your base location carefully.
Waterlogged blocks also lose their stored water when broken.
🔥 Lava
- Lava cannot be acquired using buckets.
Lava-based contraptions must be built where lava naturally occurs.
These mechanics pair well with mods that add mechanical or industrial fluid handling, requiring effort and infrastructure instead of simple bucket transport.
⚙️ Configuration (via Mod Menu)
This mod provides several configurable options:
Lava Pickup
- Toggle whether lava can be collected with buckets,
or whether doing so damages the player and destroys the bucket (default behavior).
Source Fluid Block Pickup
- Toggle if collecting a fluid source with a bucket consumes the source block.
Waterlogging
- Toggle whether waterlogging blocks is enabled.
Dissipating Waterlogged Blocks
- Toggle if waterlogged blocks should dissipate when broken.
Dissipating Ice Blocks
- Toggle if ice releases dissipating water when broken.
Persistent Water in the End
- In Better Than Wolves, water can be placed normally in the End.
Toggle this if you don’t want that behavior.
🧱 Acknowledgment
