Hey – did you ever get this working, Renaud?
I’m having a similar problem… toComp works fine (albeit, without proper 3D, obviously), but changing it to toWorld seems to take us back to square one. I thought perhaps the beam layers should be 3D, but they just sit on a flat plane within the 3D space (ie. they don’t response to the null’s movement in z space, just x and y).
Perhaps delving into Mylenium’s Spreading World Map tutorial will answer the problem, but Dan Ebbert’s response seemed to suggest that wasn’t necessary…?
Cheers!
Dylan
