Issue with water shader showing colour - URP

Hi!

Im a beginner-intermediate unity user and am currently creating a simple water shader with foam using the tutorials linked below. Ive been running into an issue where my water shaders colour becomes completely transparent as soon as I connect the foam nodes to the main lerp connecting the normals and base colour.

Im not sure what im doing wrong so if someone more experienced could take a look at my graphs that would be amazing!

Thank you :slight_smile:
