Ok, it's easy.
The "tears clothing" flows when Sim is on. Start by adding this to your person and disabling Sim, hit reset simulation just in case.
Then on your timeline, pick the moment you want the tears and set a trigger to activate the sim on the tears. Goes something like Person > jaxzoa tears > sim enabled (check on).
And that's it, tears flow at a certain time using a trigger from Timeline.
If you want stickier tears you can mess around with friction in the tears sim options.
