Leafs texture problem

[KaktuZHD]

I've trying to make trees, so I used speedtrees to create first tree. I've exported tree model to .obj format and textures in png. After it i converted png to dds. In blender I checked tree, connected alfa channel and it looks like good.

 

Then I've exported from blender .obj and opened in NifScope, so all was ok, but then I started to put textures I fond problem

 

Here you can see black color around leafs, so how can I fix it and remove this black color? Maybe something wrong with textures ?

You forgot to add NiAlphaProperty most likely.

For specific versions, Blender has a NIF export plugin I believe. It should export the proper transparency required as DY mentions. If not, then you should be able to add NiAlphaProperty to the branch node via NifSkope. Collision will be another hurdle too.
