what is the ozml vers for version 10.5.2 FCPX

I am also having an issue with this. I see all the forums where the FCPX isn't up to date therefore causing an issue with the motion template or generator not working and getting the red error. However, my FCPX version is updated to 10.5.2. However, my generator is giving me that red error. I've tried to open the motion file in text editor and changed the display version to 5.5.1 however I've had to guess the omzl number and none are working. I've tried 5.12 and 5.11.

There is probably a different reason why that particular template is not working, but anyway: i just created a template in the current version of Motion, and the first few lines look like this:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE ozxmlscene>

<ozml version="5.11">

<displayversion>5.5.1</displayversion>

I will have to check but the problem is only when using a template from newer version, not the other way around. You should be able to to use older templates without problems.
