Hi,

my second confusion about this presentation. When Scott packages the nodes into the material builder, then adds a Parameter node inside to have a Layer input/output on the packaged material. Then plugs it into the LayerMix node along with Principled Shader, there occurs a problem in the presentation itself. Scott does not fix it and instead opens a pre-made file.

I followed exactly the steps Scott did and faced the same rendering problem. I think if Scott didn't explain the reason of the error, he would be better include at least the file where it works, so we can see the result.
