Hi Tyson.
While I was testing the impact of different Time step settings I noticed the correlation of Time steps and the PhysX Velocity threshold settings.
A Time Test operator should send some PhysX particles to the next event after a few frames. This works fine up to a Time step setting of 1/2 Frame. As soon as I increased the Time steps to 1/4 Frame the particles kept their initial position and refrained from moving to the next event. Decreasing the Velocity threshold was finally fixing the issue. The more Time steps the lower the Velocity threshold needs to be.
Again, I am not sure if this is working as expected, but it was not obvious to me in the first place.
If this is not consider a bug it still might help someone else to debug their tyFlows.
Again, Thank you so much!
The screenshot shows the particles still at their initial position even at frame 30.
