Dear Wallace Adrian D’Alessio,

Thanks for your step by step explanations.
Actually I tried those steps.
But I couldn’t figure out how to achieve the goal.

I’m sure that they are helpful.

Thanks again.

Dear Filip Vandueren,

That works great for my case.

Thanks dear ….
I tried that but it was not useful.

imagine, your are going to control opacity of countries on a map with position of a null object.
when position of null object achieves to the borders of each layer (country), opacity of country changes from 0 to 100 and then from 100 to 0 while null object is crossing the country layer.

I think some codes Like this ( if … then … else .. end) can help but I’m not good in this type of scripting.

thanks again.
