LiquidSource
by kenyka
LiquidSource outlines water and lava source blocks in the client, with adjustable colors, a choice of three rendering modes and flow arrows on moving liquid.
What it does
Source blocks are drawn with a colored fill, an outline or both, and the colors are entered as ARGB hex values, so transparency can be set alongside them. Non-source liquid gets 3D arrows that point in the direction the water or lava is flowing, and the arrow color scale can be adjusted between 10% and 200%.
The highlights only change what a single player sees on their own screen, and the mod leaves world generation and gameplay rules alone. A bucket pickup indicator adds a green checkmark to the HUD when the crosshair targets a liquid and a bucket is held, showing that the block can be picked up. The configuration screen is built on Cloth Config API and Mod Menu.
LiquidSource is published for Fabric only, for four game versions, 26.1 – 26.2, and its latest file is 1.2.0 for 26.2. The mod is open source under the MIT License, and only the client needs it, so servers and other players run without it.
Key features
Source block highlighting
Water and lava source blocks are marked with a fill, an outline or both, each drawn in a color set by the player.
Three rendering modes
The highlight can be a filled shape, an outline, or fill and outline together, chosen in the settings.
Flow direction arrows
Non-source liquids show 3D arrows indicating which way the flow runs, with a scale that can be tuned.
Bucket pickup indicator
A green checkmark on the HUD confirms when a held bucket can take the liquid under the crosshair.

How it compares
Dynamic Outlines is a Fabric, client-side only option under the CC0 1.0 Universal license, open source and published for 1.21 – 26.2, so it targets a wider range of versions. HitColor is also client-side only and open source under the MIT License, for 1.20 – 26.3, and it recolors the block the player is looking at rather than liquid sources. Flow Menu is closed, under All rights reserved, and covers only 26.1 – 26.1.2.
