How to solve material transparency problem from blender to UE4 ?

So I have done a 3d model with 2 textures in blender, the first texture is for a banana image, and the second is the background color of the balloon :

My problem is when I import it in Unreal, the material seems to get problems :

And here is how is looking the material blueprint, so if someone know how to solve this problem, that would be cool :

thanks ! I have forget about this node name, now I know it’s the one named “LinearInterpolate”
and it worked so thank you ^^

your bannana texture isnt connected to anything. try using a lerp node and connect both textures. use the alpha of one of the textures (the bottom most pin) as the lerp alpha.

Please, mark the answer above as the solution for your problem.

i just converted it to an answer a few hours ago it may take some time to get done
