The maximum number of particles allowed in the sandbox. 2500
Premade simulation settings and gravity values for common scenarios. This will overwrite your current simulation settings, but you can change them back at any time.
The playground preset is great for simple worlds where you just want to mess around.
When enabled, elements interact to create new elements or change existing ones, such as lava and water making obsidian.
When enabled, living elements interact with each other and their environment, such as grass seeds growing.
The overall speed of the physics simulation. Setting this too high can impact performance.1.0
Water evaporates gradually over time, and wet elements can eventually become dry again
When enabled, gravity (depending on element mass and world gravity) may start spreading out element piles evenly to flatten them out. This includes the flow of liquids. Recommended unless you're trying to create stable structures with weaker elements.
When enabled, gravity may try to push heavier elements down and move less heavy elements out of the way.
When set to higher than 0, large bodies of water will begin to form waves and move according to their environment. This is in beta and does not work well. 0
When enabled, water will never go away after making elements wet (such as soil to mud) and therefore will be infinite.
Colour decides the default appearance of the particles
If an element is a liquid, it will have buoyancy and flow according to its solidness and density.
Evaporating liquids will gradually disappear over time.
Soakable solids will absorb liquids and (depending on settings & the liquid's properties) may eventually become dry again.
Density is the mass of the element. It affects things such as weight priority, buoyancy, and (to some degree) solidness. Water has a density of 1; anything below will float on water.
When Transformations & Interactions are enabled, this element will behave as selected.
Solidness affects the chance of piles of this element being flattened by gravity. 0 means close to a fluid, and 1 means very solid. Density and gravity also affect this, but density is not as significant.
Custom elements do not save between sessions unless you include them in a world export.
