Show icon: controls whether the tyFlow object’s icon is visible in the viewport.
Icon size: controls the size of the tyFlow object’s icon in the viewport.
Show name: controls whether the name of the tyFlow object is displayed in the viewport.
Thread count: controls the maximum number of CPU threads the flow can use to evaluate the simulation.
Auto: allows tyFlow to determine the maximum number of threads to use to evaluate the simulation (defaults to max. available)
Setting thread count to a particular value doesn’t mean that number of threads will be used for every operation, only that tyFlow may not exceed that particular number of threads for a given operation. Some operations benefit from more threads and some with less, and tyFlow makes internal determinations regarding the actual number of threads to use on a per-algorithm basis (with the only constraint being the maximum value provided by the user here).
Time step dropdown: controls the number of steps the simulation will divide each frame into. With more time steps, simulation accuracy will be increased but simulation speed will be decreased. A value of ‘Frame’ is usually fine for simulations that don’t require physical accuracy. A value of “1⁄4 Frame” or “1⁄8 Frame” is best for simulations featuring physically accurate constraints (sand/cloth/rope/etc) in order to increase overall simulation stability.
Time scale: the time scale setting allows you to control the speed of the simulation. Unlike the retimer settings, which allow you to control playback speed after the simulation is cached, the time scale setting allows you to control simulation speed as it is calculated. Values less than one have the effect of slowing the simulation, and values greater than one speed things up. N
Increasing the time scale value can lead to physics/PhysX inaccuracies, because increasing the value increases the velocity of all particles within the time step. You would only use this setting, as opposed to using the retimer, if you need to change the simulation speed of particles while maintaining the speed of all scene objects your particles are interacting with.
It is always recommended to use the most recent version of tyFlow.
