I've made End credits title in Motion, and It fairly often glitches in FCPX, and on export.
Sections of the Motion Title just don't show up on export, or just don't show up in FCPX. The only fix I've found so for is to delete all render files for the FCPX library, and then restart the computer. Oddly enough just relaunching fcpx doesn't seem to help.... Sadly this only temporarily fixes the issue.
I've included pictures to illustrate what I mean. (as well as system specs)
In the one screen shot it shows the credits on black (which is wrong)
and the other it is how it was made in motion with a yellow backdrop of grass blowing.
system specs attached...
We are working from a Jellyfish tower, and our Library Cache is held on it as well. (NFS). Could it have something to do with the Cache on the server?
