I was trying to use goalU condition on the particle,
like : if (goalU < .5)
and then I found the particle doesnt respond correctly as expected.
later I found out it's the primitive nurbs obj I created has UV value higher than one,
for example, it's a cylinder and has 20 span on U, and the max U value will be 20 instead of 1,
That's really a big conflict again what I have known before.
Shouldn't the UV value of nurbs always fall between 0 and 1??
Well at least it's what it looks like in the UV editor.
So I think I must have missed some knowledge here...
Could someone fill me up please?
