Importing models often not possible

[spookyboo]

The import model plugin (AssImpPlugin) makes use of the assimp library. However, a lot of .d3s, .obj or .blend models cannot be imported, although the Ogre xml is created. Error in OgreMeshTool.log:

13:54:52: OGRE EXCEPTION(5:ItemIdentityException): Cannot locate an appropriate 2D texture coordinate set for all the vertex data in this mesh to create tangents from. in Mesh::suggestTangentVectorBuildParams at C:\Users\Henry\Documents\Visual Studio 2015\Projects\ogre2.1\OgreMain\src\OgreMesh.cpp (line 1850)

Is this a bug in assimp or is Ogre too strict?
