needless to say this is not supposed to happen, it was just working the other day and now when i try to morph target the avatar's geometry completely breaks. does anybody have any insight on how to fix this? im only doing morph target because i also cannot load animation files without it being broken in a completely different manner. why is this software so buggy?
This happens when your imported mesh (morph) has the wrong x,y,z axis orientation or vertex mapping. You have the correct vertex ID count BUT your mapping from the original vertex's (x,y,z) to morph are wrong.
This can occur when your exported mesh has a change in the world space x,y,z orientation (on export) or that the scale is not correctly applied in the origination model prior to any shape blend (keyshape). For example in blender you need to ensure you apply all transforms to the 3D model and morph (keyshape) on export otherwise you could end up with a morph target that has it's x,y,z mapping incorrectly aligned in the next app. In blender there is an apply all modifier toggle on export option for example - check that.
