Morph Targets and Animation
I have been dealing with this for a while now so I decided to ask here. (Sorry for this being so long, I am trying to be as descriptive as possible.)
I am trying to create a simple character customization for my WIP project as seems logical I reached out to Morph targets my workflow is as follows:
Everything works fine IF I do not change the height of the model using a morph target for height. And by everything works I mean all the animations behave as expected, all non height related morphs do modify the mesh as they should etc..
But once I modify the height morph target this happens:
The body and the hands get significantly deformed.
Please note this is a Mixamo based animation, but happens the same on retargeted Mannequin animations.
Significant things to note: - The morph targets look ok when there is no animation playing - In Blender if I move the bones while the shape key value is modified there is no deformation happening - If I import the animation into Blender the mesh gets deformed as well.
The skeleton bones are
Things I have tried so far: - Change the pose from A to T (Easier retargeting from Mixamo) - Uploaded T pose character(with Morphs) to Mixamo and let them do their work - Uploaded T pose character(without Morphs) to Mixamo and retargeted to morph capable model - Changed all settings that came to mind during the import(Smoothing groops, update skeleton pose, use T0 as ref pose and others) - Used UE4 4.19-4.21 to try things out
The skeleton I used in Makehuman is GameEngine(tried it with others as well with no change), for the A pose I used a blender script to get the bones to the correct position and adding the twist bones(so it is more or less compatible with UE4 skeleton). This is why I tried the T pose which is just plain T pose with no extra modifications done during the morph target creation process.
I am pretty sure I am missing something obvious somewhere, did anybody run into this and managed to resolve it? Any ideas what to try?
I understand that this is probably the animation issue as it happens both in UE4 and in Blender, I also tried multiple from both Mixamo and the Engine content and all have the same issue.
