Hum… thanks, I will check.
The weird thing is I can get all the info if I load my FBX file in a new empty Blender project.
From what I see, it rather looks UE4 doesn’t translate all FBX datas (or more exactly refuses to consider shape keys without bones : no bones = staticmesh VS bones=character). The weird thing is UE 4 process 3DSmax morph target but not Blender ones. The UE4 doc mentions FBX to import morph target, so…
The thing is UE add a “fbximport” when FBX are from Blender when Orwen morph target is recognized as an animation. But without bones UE4 don’t recognize Blender animations… kinda strange. FBX is supposed to be standard…
But, anayway, I will try some add-ons to see if I unlock something.
