uhm, I'll explain this to you
First of all, you make your particle emitter.
Next, tick the Animated box in the Visibility (I don't how to name this, the one where the )
Then Click the Visibility box
Stop here.
Open Sequence Manager.
Lists down all the intervals of all the animations.
Let us take the Blacksmith as an example.
Birth: From 3333 to 63333
Death: From 86667 to 88333
Decay: From 88500 to 148500
Portrait: From 76667 to 80000
Stand: 65000 - 65167
Stand Work: 66667 - 70000
So we want our particle emitter only shown on the "Stand Work" animation right?
Back to the first. (Where you open the Visibility Box)
List down every 'From' Intervals (Also removed that 0: 1, we don't need it)
3333
65167
66667
76667
86667
88500
It is important to arrange the 'From' Intervals from least to greatest.
Then add 1 or 0
3333: 0
65167: 0
66667: 1
76667: 0
86667: 0
88500: 0
Why?
because 0 means off and 1 means on
so 66667 is the 'From' interval of the Stand Work anim right?
So from 66667 until its 'To' interval, its on.
That's it.
