Buoyancy Field

Pro Feature

Pro features are only available with a Professional licence. Starter licences can evaluate most Professional features via the Try Pro button at the top of the Viewport. To upgrade, visit cavalry.scenegroup.co.

Intro

Create fluid containers where bodies will float or sink based on their density within a Forge Dynamics simulation.

Common Attributes +

Size - Set the dimensions of the fluid container.

Fluid Density - Density of the fluid. Bodies with lower density will float, higher density will sink. Compare this to the body's density (set in Forge Dynamics Shape) to control behavior.

Buoyancy Strength - Multiplier for buoyant force. 1.0 = physically accurate, higher values create stronger upward push.

Drag Coefficient - Resistance to movement through the fluid. Higher values slow bodies down more (opposes velocity).

Lift Coefficient - Force perpendicular to velocity direction. Creates swirling/spiraling motion in the fluid. 0 = no lift.

Angular Drag - Resistance to rotation in the fluid. Higher values slow down spinning.

Uprighting - Apply rotational force to make bodies orient themselves to a target angle (self-righting).

Uprighting Strength - Strength of the righting torque. Higher values make bodies rotate to upright angle faster.

Upright Angle - Target angle in degrees that bodies try to rotate towards.

Affects Groups - Enter comma separated strings (e.g. text, rocks) to target/filter specific Collision Groups for a field affect. Collision Groups can be added to bodies via the Forge Dynamics Per Body Settings.

Falloffs - Connect a Falloff to isolate where in the Composition the Field is active.
