There’s a basic slope/height material in the project based on some tutorial code I found that you can try out. I use Dokyo’s low poly asset packs from the marketplace for materials/meshes on my private repo.
Back from my travels…haven’t slept in 32 hours but I thought of a couple of silly mistakes in the code while I was on holiday and just pushed a small update to resolve them (Normal and tangent calcs were being duplicated 4 times, oops).
