1.Solver Property
Parameter | Description |
|---|---|
Simulate | Garments simulation switch, garments will not simulate after it is turned off |
Self Collision | Clothes self-collision switch, turning on self-collision will prevent clothes from intersecting |
Async Mode | Asynchronous simulation mode, asynchronous simulation mode has higher performance |
Animation Mode | Animation mode, if the character skeletal mesh has no animation data, this option can be turned off to improve performance |
Smooth Animation | Smooth animation, which can alleviate the problem of unsmooth animation of the character's skeletal mesh in the initial period of time and enhance the stability of the simulation |
Back Face | Whether to render the back of the clothing patch |
Side Face | Whether to render the side of the clothing patch |
Collision Convex | Clothes generate collision bounding volume switch, which can accurately support ray detection, mouse picking and other functions after it is turned on |
Fictious Force | inertial force switch |
Strain Map Color | When on, the amount of clothing stretch will be written into the vertex color. The material node reads the color and renders the result. |
Solver Type | Solver type |
GPU ID | GPU serial number used for simulation |
Time Step | Simulation time step, it is recommended to set it to the reciprocal of the FPS displayed after Play (1.0/FPS); if set to 0, Time Step is automatically adjusted according to the time interval of each frame |
Substep | Substep Each frame of simulation will be decomposed into multiple substeps according to the value of substep, which is suitable for scenes where the human model moves a lot or the project is locked to a lower fps |
Iteration | The number of iterations to solve, the higher the value, the more accurate the solution result and the greater the computational overhead |
Gravity | The acceleration of gravity when the clothing is solved |
Damping | Air resistance encountered when clothing is solved |
Self Collision Stiffness | Self-collision strength of cloth pieces when solving clothing |
Extra Thickness | Extra collision thickness, the larger the value, the less likely to penetrate, but the larger the gap between clothes |
2.Precautions
When adjusting parameters
● The time step length Time Step does not exceed 0.03
● Self Collision Stiffness not less than 0.5
●The higher the clothing cloth physical property value, the higher the number of solver iterations required
