    Hi,

    I'm thinking of implementing a height map overlay on my level geometry. I've not done this before but from a quick google it seems I may need tessellation features in my shaders. Can we do this in URP?

    No, first of all, let me clarify something: tessellation isn't necessary (but is recommended), You could just sub-divide the object / models in the 3d modeling software of your choice. But however in urp to do the tessellation, you may need to use shader graph.

    Subdividing the model creates a denser mesh with larger storage requirements.

    Tesselation does it a runtime

    Amplify Shader Editor does tesselation out of the box
