Expressions
 

Hi,

I have created an expression that reacts to wind problem is i do not want it to start until the wind gets stronger.

Can i either use a greater than condition or can i set the expression to start on a set key frame ?

I would imagine you should be able to set the expression to start when the wind is greater than a certian value.

Any idea how to ?
i actually got around it by adding in two wind effectors and just starting one furture into the timline but would be useful to know how to do conditions in expressions.

Eeks expressions are mysterious to me I just know a little about how they work. I know in the Inside Lightwave 6 book it covers expressions in a fairly lenghty chapter just never got around to useing them.

Here is a couple links to some expressions tutorials.
