Convert Motion template to FCPX Generator
I have just purchased a Motion template for a photo slideshow. When I convert the template for use as a Generator in Final Cut Pro X, I lose the ability to access the editing parameters. For example, I can select a photo and it will be added to an empty Drop Zone in the slideshow. This is fine so log at the photo is landscape. When I add a portrait photo, I need to edit its size, shape and position. The parameters are visible to do this but they are greyed out. In Motion, all the parameters are showing as 'Published' so I'm at a loss to work out what the issue is. I'm using Motion 5.4.7 and FCPX 10.4.10. I have published from Motion as both 'Title' and 'Generator' and both react the same way, the resizing parameters are greyed out.
I'm an old hand on a Mac but Motion isn't something I'm familiar with in this way.
Any help is greatly appreciated.
