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 :

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.

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

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
