Missing/Transparent faces on mesh

I am trying to import a model into unreal but when i do, some of the faces are missing/transparent. I have tried removing double vertices and flipping the normals inside of blender but it doesn’t fix it. any help is appreciated

model in Blender

model in Unreal

Well this is a common issue my friend and you need not worry.

first of all have a look at this video .

then what you can do

  1. is select your mesh
  2. go to edit mode
  3. press space
  4. select triangulate faces option.

hope this helps If you issue is still not going away then I’ll try finding any other solution that is leading to this problem …
But, I think it would work.

triangulating the faces didn’t seem to do anything, but after watching the video I realized I forgot to change the scale in blender. After re importing with the fixed scale the model looks normal. Thanks for the response!

hope you get your desired result . Let me give you a suggestion , always be in the search of addon for blender . I assure you they are great.
Good luck my friend with your project .
