How my rigged model looks in blender (weight is properly assigned to bones) and how it looks in Unity (weight is messed up).

I had this exact problem the other day D: but with Maya, the skin said it had weight information in Maya but then i imported it into unity and got that result.
Basically i went back and deleted all the non deformer history off the model, then painted the weights again, making sure to select the affected verts and flood them with a weight value. The problem also occurred when i exported it into motion-builder.
Unity should say that it could not find the weight information for verts in the import log, check there see if it is a problem in the skin.
Yes, the unity compiler did say something like some of the vertices don’t have weight assigned to them. So I went to blender and found that tiny sections hadn’t been weight-painted. After weight-painting those, the model looked exactly the same in Unity. Any idea?
