How to put transparent textures in 3d?

[Alike]

I'm new to wallpaper engine, I recently tried to make a new project, and imported an obj model, all right but the textures, however, the leaves of the trees should be transparent but instead it comes out with a black background, png and tga format, any one has a solution? I would like to continue continuing with my project.
