Sm5 problem float 2 and float3

Hi everyone, my name is Matteo and I have a problem with the material function. I have just created sandy material and now I have to create a feature, but I am experiencing the SM5 problem. As you can see on the photo. How can I solve it.

I think you’ll need to either append a vector or transform the float2 to float3 somehow (there’s at least one node that does it).

Thank you so much. I’ve just solved

Was that basically the solution? transforming the float2 to float3 somehow?
