UV Materials wont transfer from Blender to Unity

[Eithman]

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

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

What's up with all these different Normal map formats?

Blender is +Y. Did you remember to rebake normals after switching in Painter? Blender’s OpenGL viewport uses, well, OpenGL, so it naturally evaluates normal maps in OpenGL. It makes sense for Cycles to use the same as the OpenGL viewport. There are fortunately only two common formats, which isn’t that hard to keep track of. I agree it would be nice to have only one, but with two major engines, Unity and UE both using different formats, it’s easier to learn the distinction. You just need a nod…

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?
