Hair textures done in Substance not rendering well in UE4

Hi, So I created my hair sheets in Substance with a smart material for hair, then in Max I placed the planes to create the hair of my character, when rendering into max the hair were ok, then when I exported the maps (base color png with alpha channel and normal map) and mesh to UE4 the result is horrible, to actually see the hair result I have to zoom in the head of the character because from far the hair just disappear, its my second week using UE4 and I’m not that lost, maybe it have to be with the lighting or the shader of the hair that can be very complicated. If someone can recommend a good workflow for archive a basic hair I’ll do my best. Thanks
