I am having the same problem that my cloud does not run smoothly between 2 hours. For example, in the first hour I get the json value of windSpeedOfJson=3.6f, dirXByJson=0, dirYByjson=1, then I will lerp the values from 0 to those json values. But when next hour I continue to get values from json windSpeedOfJson = 3.0f, dirXByJson = 1, dirYByjson = -1, now my clouds run not smooth and sometimes run backwards. I’m looking for help hoping you can help me.
You can debug that better by looking at more/all values.
But, I’m guessing it might be from currentTime or totalTime use. Stuff like that can do time based things like you see there.
