Why Blender exports to UE models with specular?

[WDRK23 (WOODREK)]

Hi!! As it says in the title, I’m confused why my Blender models are exported with Specular in UE when they are Shade Smooth in Blender, but when they are without Shade Smooth then they are exported without Specular

Left - without shade smooth;
Right - with shade smooth

How could I fix this?? From the Blender or?

Both have specular it just a matter of normal interpretation.

Adding to what 3dRaven said, the problem here is how your smoothing groups are being interpreted.
To understand more about it I suggest reading: Smoothing Groups - polycount

Thank you both very much!!
