Our team is having a problem importing morphs onto our character. We have a bunch of morphs (.MOR exported from Max) for our character - each of them contains 10-20 channels and an animation corresponding to an animation clip also from Max (FBX exported). What's happening is once we import ~25 morphs onto our character, importing additional ones causes Unity to become unresponsive for about fifteen minutes and then the morph is successfully available. All morphs prior to this take only seconds to import.

I attached MonoDevelop's debugger to the MegaMorphEditor script and it looks like it's completing the entire morph import process successfully, marking the inspector dirty, then returning from OnInspectorGUI. Some time soon after that, Unity hangs. I tried getting more information (logs, a stacktrace, etc.) but was unable to figure out anything. If I removed morphs after it got to a state where it seemed "full", I was once again able to add more morphs until I got to ~25 again.

Each morph is somewhere between 100-200KB (claims the "Channel Compressed" field). Also each morph contains only a single animation (the same length as a corresponding anim clip we'll play simultaneously).

Anybody experience something similar or have any ideas for how we could handle/workaround/fix this?

For our character, there are many FBXs (one for each animation) and many MORs (again, one for each animation). We probably have close to 50 pairs for our main character.

Yeah, there are many Morphs on a single object. At startup we disable all of the morphs (set animate to false and reset the channels), then when we want to play any particular animation clip and morph pair, we start playing the clip and we set the animate field for the corresponding morph to true and reset the animtime to 0. Is there some better way we should be going about this? Our animator would like to continue using Max to animate the bones and the morphs.
