I am using Element 3D and have two 3D layers. I want to link the World Transform values XYZ Positions, Scale and Rotations.
Is there a simple expression, something similar to thisValue.sameAs("Layer 1") ?
I am assuming it might be tricky to find the names of Element3D's unique properties for use in expressions.
You have to compensate the Element 3D coordinates so they match the comp settings. I do not use Element 3D so I'm not sure exactly what the setup is, but other 3D effects tend to use half the height and half the width of the layer as zero. If that was the case then position would be modified for X would be modified by adding half the layer width of the Element 3D layer to the X value for position in Element 3D.
You'll find more help on the Video Copilot forms on this question than here unless an Element 3D user finds the thread and they are familiar with writing expressions.
If you were to send me a screenshot of the Element 3D interface showing the position and rotation values you want to match to AE's comp space I'll give it a shot.
Thanks for your reply. It turns out it is a simple matter of Pickwhip-Linking the properties of one layer to another. I just didn't realize that you could do this with individual properties after Alt-Clicking the keyframe icon.
