model have some white light

Hello Guys. I am a beginner in Ue5. I imported this model that I made in blender to UE5.4.
and even tho I didn’t assign material, there is white light in the eye and in the teeth. I tried normal and tangents. export and reimport new model. yet it still happening. Help! I can’t find anything about this in internet.

Using the ‘Highlight’ and ‘Isolate’ options, you can see what each material element is within your mesh. Check either of these options to see which one is the white material. But ultimately, you have no material assigned for ‘Elements’ 0, 2, 4, or 5; therefore, UE is rendering that portion of the mesh with the default grey material.

Select a material for those elements to see their proper colors.
