Hi...
The content file formats that can't be exported are shown below. This has always been the case and isn't something new.
.iTree, .iTerrain, .iSky, .iMtl, .iMtlPlus, .iLflare, .iPkfx, .iEffect, .iAtm, .ccLightRoom
So for example, you may see the "non exportable content" warning for hairstyles that contain .iMtlPlus files to change the hair colour. This doesn't mean the hair itself can't be exported.
