Calibration Tools

Gravitational acceleration. The real engine default is 9810 (9.81 m/s²). Lower values slow free-fall for large touchscreen displays.

2D circle-packing density used when converting charge volume to particle count. 0.82 is the theoretical hexagonal close-pack limit.

Constraint solver passes per substep. Higher values stiffen contact and reduce overlap jitter at the cost of CPU.

Maximum physics substeps per render frame. Higher values keep fast rotation stable but cost CPU.

Maximum particle speed before the solver clamps it. Prevents numerical explosions during unstable cataracting.

Hard cap on rendered particles. Lower for smoother performance on older hardware or large touchscreens.
