So I just finished modelling my Scar H but I noticed this it has some blue and white parts in it and when I import it to UE4 and Unity half of the blue parts was gone am I doing something wrong?

In UE4 when I import it it says "the model has degenerate tangent which may cause incorrect shading"

  • $\begingroup$ Quick google on the exact error message shows UE4 forum posts about dealing with it, may be worth reading $\endgroup$ – zeffii Jun 20 '15 at 7:28
  • $\begingroup$ Blender.StackExchange is here to spread knowledge which can be used by more than just one person. If you care to share the .blend or can localize the problem area and just share that part in a .blend, then we can rewrite the question to include something that people can cross reference (before, and after) if they get that error too. Else this question might be considered too narrow and get little attention. Which would be a shame. $\endgroup$ – zeffii Jun 20 '15 at 7:34
