Got a Texture_Normal Problem (maybe UVmap Idk)

Hi Everyone,

So I got this blender model and I am trying to bake the texture to unreal. The texture did baked and look the same in blender. It also looks good without the Normal map plugged in, but as long as the normal is in, there is this weird pixel glitch in the shader after I compiled it in UE. Initially I thought it’s the resolution so I baked a 2k and 4k version but it is still showing up the same.

that preview of it certainly doesn’t look like a valid tangent space normal map. check your bake settings in blender. can’t tell exactly what option you ticked.
