Lip Sync 4.6

NW316

Hello,

I've been experiencing a problem when transfering characters into 4.6 to animate lip syncs and then bringing them back into 4.8 for rendering in iRay.  It seems if I have a character with iRay uber base on it, 4.6 looses the eye materials and after lip syncing and saving, then transfering back to 4.8, I cannot reconfigure the missing eye materials for rendering.  Any advice very much appreciated.

Thanks!

Don
