Make Objects Float or Sink in Water

Understanding Buoyancy

The Primal Aether Surge Mod applies realistic buoyancy to physics objects based on their material density and shape. Lighter objects and those with larger surface areas relative to mass will float, while denser items sink.

Setting Up Floating Objects

1. Spawn or convert a block into a physics object using /vxsummon or by enabling physics on existing blocks

2. Place the object near water or lava

3. The object will automatically respond to liquid based on its properties—no additional configuration needed

4. Objects made from wood-like materials typically float, while stone and metal sink

5. Use the PhysicsGun to adjust object position if needed before releasing it into liquid

Testing Buoyancy

Use /vxtest to spawn pre-built soft body and object setups to observe how different materials behave in water. This helps you understand which block types will float versus sink in your builds. You can then use this knowledge when creating floating platforms, water transport systems, or decorative elements that interact realistically with liquids.
