Hi
apply your tracking data to a null,parent your explosion layer to that null.I think this way it should work:-)

Hi
one way
create two sliders rename it to x + y for example
add this expression

x=thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”);
y=thisComp.layer(“Null 1”).effect(“Slider Control 2”)(“Slider”);
z=position[2];
[x,y,z]

but let’s see what dan or mylenium suggest

Hi
[tommmm] “I made a 2600×1950 text image (white text, black background, PSD file).”

You don’t need a background,that’s the reason why your Alpha Matte doesn’t work.It would work if you’d use a Luma Matte instead of an Alpha Matte 🙂

Hi again
I’ve got one more question concerning the second line of the expression.
instead of using {opa=0},you can use any other words and it still works.Why?
Does this line automatically refer to the parameter which the expression is applied to?In this case opacity.
Thanks for your patient.
