fix tangents

[demostenes]

3ds max has issue with fbx export and tangents, it is exporting tangents in FBX per face average instead of per-vertex. It would be handy to have some option to recalculate tangents (for example in unigine resource editor, or new asset browser). Exactly this is reason, why Unity and UE4 have this functionality in fbx importer (http://www.dropmocks.com/mIb93Q). Problem is described here:

I know you are preparing new asset import pipeline, so this is hint for other improvement :)

Thank you for your suggestion!

 

I've added it to our internal bug tracker. Can't promise, however, if this option would be available in the first asset browser release.

We also have some options to manipulate a tangent space in ResourceEditor. For example, Flip tangent and Seamless tangent (available after clicking the Smooth Mesh button).
