Skeletal mesh 2D character Z sort priority with same MAT

Hi! I have this skeleton mesh with a single texture and material.
Parts are correct in terms of depth (z). I exported from max.
The problem is that I cant find the way to do a proper sort parts in depth because all the skeletal mesh is a single object. Any help?

ummmm changing translucency material property to masked solved it.
Why transluscent cause this issues?
