Hi! I’m trying to import a character model with morph targets but I just can’t get the morph targets to show up in Unreal 4.27. I’m using Blender 3.3.0 with the Blender File Import plugin from the marketplace.
I have looked around and tried different things including:
Making sure the “import morph targets” is checked in the import window
I have tried removing and recreating the morph targets
Reimporting the mesh, both dragging it into the editor, clicking the reimport button in the skeletal mesh viewer and reimport in the right-mouse menu in the asset browser.
Made sure that the model imports with at least one animation (for some that was the fix, not for me)
renaming the morph target keys.
I have tried creating a new blend file with an unrelated model just to check if the importer plugin is the problem but that new model’s morph targets works just fine.
Restarting the editor
Nothing that I’ve tried seem to work, it seems like UE just can’t recognize that the file includes morph targets? Can someone maybe explain how UE handles morph targets so that I can prossibly trace the problem backwards? I could recreate the model from scratch but that’s a whole lot of work remodelling, UV, rigging and animating that I’d rather not redo and even then I’m not sure it will work.
to export I check if I am in object mode and just select the mesh and the armature
(I just hide everything else and drag a rectangle of the whole to select)
then I just export with default built in blender FBX exporter (no marketplace plugin)
Thank you for taking the time. I tried that but it doesn’t work for my character model. It works great if I create a new blend file like you did. I suspect that there’s some sort of problem with my character model though I’m not sure what.
Here’s the blend hierarchy and the Object data properties. If there’s something off about it I’d love to know. If you want some other info I’d gladly share that.
I spent a chunk of the day reacreating a brand new character model, rigged it and set the morphing target. This one also does not work. Is this a bug or am I unaware of something? I know that when exporting animations you need to rename the armature to something else or the scaling doesn’t work. Is there a similar quirk I need to be aware of when exporting morph targets?
Edit: Alright, so I got it working now. Seems like you can’t have modifiers and shape keys at the same time. Removing the modifiers and unchecking “add modifiers” on export did the trick.
