How to Properly Import .FBX Blender Files into Unreal4?
Hello, I am having difficulty importing my ".fbx" from Blender into Unreal Engine 4. The error I am receiving says the model has "degenerate tangent bases, which will result in incorrect shading". Unreal and Blender are fully updated and I have the newest versions. I am on Windows 7 and have tried it on Windows 10 as well as a Mac so I know that isn't the problem. I've tried it on Intel graphics and Nvidia graphics so that isn't it either. Also I tried multiple .fbx versions such as FBX 7.4 binary and FBX 6.1 ASCII already. I tried different computers that had 4, 6 and 8 GB of RAM. The processors I ran it on were Intel 2.3 GHz and 3.3 GHz. Also the computers were running at 64 bit. Is Blender compatible with Unreal? And if so how? There are no tutorials online that have helped or shown the correct way to import into the Unreal Engine without errors. I've searched high and low across multiple websites for the answer but I have had no luck. Blender was not helpful at all when I emailed them. Please help!

When exporting in Blender I set the smoothing to "Binary" and under "Geometries" change "Smoothing" to "Edge". This may help with the degenerate tangent bases.
The cause of most issues with Blender (my preferred modeling tool for price reasons) is Blender's FBX export. Even people using other engines have issues with it. https://www.google.com/search?q=blender+fbx+export+issues&oq=blender+fbx+export+issues
This video by Epic is pretty helpful: https://www.youtube.com/watch?v=Ayp1lof0RJU

The model has "degenerate tangent bases, which will result in incorrect shading" It means you have not uv unwrapped your model
