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. Please help!
