UV Materials wont transfer from Blender to Unity

I made a taco in a VR modeling program called Medium. I imported that into Blender in order to retopogize it. I then UV mapped it and applied the UV material and normal maps from the original version of the taco onto the retopoligized version. Next I exported it as an FBX and imported it into Unity. I selected it, clicked the materials tab in the inspector and extracted the materials. The problem is that they are all just default gray materials rather than the color mapped ones from Blender. Any idea what I am doing wrong? Here is a dropbox link to the file I exported from Blender. https://www.dropbox.com/s/x32n9jnil2xxhvq/tiffsyummytaco1.fbx?dl=0

maybe this https://docs.unity3d.com/Manual/HOWTO-ImportObjectsFrom3DApps.html#Blender

I followed that link and looked up several tutorials on youtube but I am still having the same issue. Is transferring UV maps and normal maps from Blender to Unity usually this complicated? Is there a go to tutorial anyone can send me that covers this and works for the latest version of both programs? Thanks in advance!

did you see that one

happy cl

I actually tried to simply apply the UV and Normal maps I made to the retopo’ed object in Unity and it seemed to work for the most part… I do get some odd glitches, though. Is there a step I’m doing wrong or something I should be paying closer attention to to prevent this?
