Material importing problem and degenerate tangent
Hi Everyone! I'm new to UE4 and I have few problems with it. First, when I import my 3D model from Blender I recive a message ,,Object has degenerate tangents...". I searched for a solution, but found nothing. Some walls have good shadows, else are black. Second problem is when I import my model and add it to 3D view in UE4 some materials aren't properly imported. They are blurred or don't look like original materials from Blender.
Here are screenshots:

Message about degenerate tangents is not an error, and is just warning. And this usually happen, when your model not have UV map or UV map is not correct.
Before export, you need collapse all modifiers in stack, check normals and UVs on objects. Each object must have UV0 for texture and UV1 for Lightmap.
This is several tutorials about how to prepare models for export from Blender to UE4.
