Solver#
Reference
- 패널:
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.
