Blender Tree Won't Render Correctly

So I made a tree in Blender and it is doing this

The shader I am using is this:



Also I imported the asset as an .FBX and with all the normals calculated in the engine and the faces imported on the curve. Did I do something wrong is this some glitch?

 

Well I fixed the bark issue but now it won't show the leaves. That is to say the engine will not render the imported leaves on the .fbx game object.

 

since no one responded to me I am going to have to assume that this problem is a program issue and not an issue on my end.

 

That's a silly assumption. More likely - because nobody responded it is probably something you are doing wrong rather than something program related that others know about.
Though it could be something that is documented and known about and others assume you might research the issue to find others may be having the same problem.
Unfortunately I can't help - I don't use blender nor am I currently working on environmental stuff.
