🌊 Physics Realistic : Ultra Realistic Physics

Realistic water, lava and sand physics for Minecraft Bedrock, made of flowing particles, with an in-game settings menu.

Physique Réaliste: Realistic Water, Lava & Sand

Water, lava and sand that fall, flow, pile up and spread like the real thing, using only Bedrock's scripting. No shaders needed.

Features

- Realistic Water: made of linked particles that flow, spread, pool, fill holes and run down stairs and over ledges. It puts out fire and cancels fall damage.
- Realistic Lava: thicker and slower than water. It sets entities on fire, and turns into cobblestone when it meets realistic water.
- Realistic Sand: every sand block becomes thousands of tiny grains that pour, slide and pile up. Grains pass through grass and flowers without breaking them.
- TNT: primed TNT floats and is pushed by the water, and its explosion throws the water out.
- 24 languages: the menu and the item names follow your game language.

Settings menu

The menu opens when you enter a world, and any time with /sr:menu. You can change:
- the number of water, lava and sand particles (or pick Low / Medium / High)
- the speed of water, lava and sand
- the size of the sand grains (bigger grains = much less lag)
- the view distance: far particles disappear and come back when you return

Commands
/sr:menu - open the settings menu
/sr:clear - remove ALL particles and sand grains (anti-lag)
/sr:drop [number] - pour a cloud of water particles in front of you
/sr:droplava [number] - pour a cloud of lava particles in front of you

How to use
Find Water, Lava and Sand (Réaliste) in the creative inventory. Place a water or lava source with a right-click. Enable both the Behavior Pack and the Resource Pack in your world.

Tips for mobile and low-end devices
- Keep the quality on Medium or Low.
- Choose Medium or Large sand grains: this lowers lag the most.
- Lower the view distance (for example 24 or 32 blocks).

Good to know
- Inspired by Java physics mods, but not the same: Java mods use shaders, which Bedrock does not allow. Here, water and lava are drawn as linked particles, so you can still see separate drops.
- The water texture has an optional reflective effect. It needs Vibrant Visuals and may not show on every device.
