Pannello:

Physics ‣ Soft Body ‣ Solver

The settings in the Soft Body Solver panel determine the accuracy of the simulation.

Step Size Min

Minimum simulation steps per frame. Increase this value, if the soft body misses fast-moving collision objects.

Max

Maximum simulation steps per frame. Normally the number of simulation steps is set dynamically (with the Error Limit) but you have probably a good reason to change it.

Auto-Step

Use velocities for automatic step sizes. Helps the Solver figure out how much work it needs to do based on how fast things are moving.

Error Limit

Rules the overall quality of the solution delivered. The most critical setting that defines how precise the solver should check for collisions. Start with a value that is half the average edge length. If there are visible errors, jitter, or over-exaggerated responses, decrease the value. The solver keeps track of how «bad» it is doing and the Error Limit causes the solver to do some «adaptive step sizing».

Diagnostics

Print Performance to Console

Prints on the console how the solver is doing.

Estimate Transforms

Estimate matrix, split to COM, ROT, SCALE.

Helpers

These settings control how the soft body will react (deform) once it either gets close to or actually intersects (cuts into) another collision object on the same layer.

Choke

Calms down (reduces the exit velocity of) a vertex or edge once it penetrates a collision mesh.

Fuzzy

Fuzziness while on collision, high values make collision handling faster but less stable. Simulation is faster, but less accurate.
