Resolved See trough material with strong border

Hello, I am new to the forum and already posted this to the shader department, but I am not sure if it is right there:I am quite a newbie when it come to shaders.

What I want to do is, that my hex based maptiles are see-through and only the edges are visible. My problem is now, that when I make my shader into a material and put that on my hex the hex is not see through.

My shader: https://ibb.co/VW4dbFk
Note:at PBR Master I set the shader to transparent
The tutorial I followed for the shader:

The model I am draging the material, created with the shader on, is a cylinder with six edges imported from blender. It doesn't have any texture

 

Your visibility is still controlled by the alpha input in your master node.
Connect your multiply node with it or one of its channel.

 

thank you for your help, I tried to either connect multiply or base colour to the alpha input, both didn't give me the results I wanted. Still not see through. Which leads me to the question if fresnell is actually the right effect for my problem.

Do you maybe know a diffrent effect, which end in similar results?
