Motion Crashing Lots In Yosemite

It got worse and worse as the project got larger and larger. Not the largest I've done, but pretty serious. Now, I can't export at all. If you live off of Motion 5, put off the Yosemite upgrade until the next Motion release. At least until the next mObject release, if you use that. I had problems with crashing often when I edited 3D text in that generator. Never had that issue before.

I also have my screen going blank for a second, ever 20 minutes or so, while working in Motion 5. I verified I disabled my System prefs to NOT put the monitor nor the Mac Pro to sleep.

I had a second, complex project that gave me similar issues to the one that had mObject in it. The only commonalities between the two, using mRays and mDust clips in both. Both are 1080 format and 30 seconds long. And both are generic Motion projects, not FCPX templates.

FCPX templates are having no issues at all for me.

Try to convert all your generic projects with problems into FCPX project templates.

FYI, MotionVFX claims issues aren't with mObject, but the number of emitters and replicators I was using.

I made several versions of this Motion project, isolating sets of layers in each. The ONLY one to crash, and not export at all, is the one using the mObject layers.
