| The reason is that the first object becomes invalid once you run addProperty again. You can add the properties back to back like in version 2, but you would need to assign them to variables afterwards like in version 3, to be able to access any attributes for them. VERSION 1
This works because you are changing a value to a valid effect property immediately after creating each effect. VERSION 2
vppath becomes invalid the second you add another property (vp), at which point you cannot change something that's invalid. You can check if a variable is valid by running: vppath.isValid; vp.isValid; Doing this though, should work. VERSION 3 //Create effects curLayer.Effects.addProperty("VP-Path"); curLayer.Effects.addProperty("Virtual Projector"); //Assign effects variables var vppath = curLayer.property("ADBE Effect Parade").property("VP-Path"); var vp = curLayer.property("ADBE Effect Parade").property("Virtual Projector"); //Change properties vp.property("Azimuth").expression = ("50"); vppath.property("Azimuth").expression = ("50"); ------ David Torno Visual Effects Artist and Supervisor O: 213.739.2290 C: 818.391.6060 ------------------------------------------------ http://www.sydefxink.com (main portfolio) http://aeioweyou.blogspot.com (vfx tutorials and AE scripts blog) http://mactex.blogspot.com (free textures blog) On Jan 19, 2014, at 2:01 PM, Drew Gilmore wrote: Thanks yeah, now that I poke around it's clearly something else I'm doing wrong...
