I'm having a problem creating a shader in the strumpy shader editor. I want to create a shader that has a mask for the reflection and specular and also a fresnel falloff for the reflection. But when I create the shader it comes up with errors. When I remove the cubemap and replace it with just a colour it works fine. Or I can replace the diffuse with just a colour and it will show the reflection and specular. I can also replace all the specular maps with the diffuse map and it works. Is it even possible to create a shader that does this or is there something wrong with the code that strumpy makes? picture of graph (The problem area is in blue)

Any chance you could post an image with the final Shader? I'm trying to learn a bit about this and I could really use som examples. Thanks.

I solved the problem. I just used the alpha channel of the diffuse map for the specular level. It's a good technique to use if you just want a grey scale image.
