I use HDRP, i never tried URP but HDRP gives way more control while looking awesome, also the Post Processing stuff is amazing
For the Materials, i amde my own Material using Shader Graph so that way i can use Ambient Occlusion and Roughness correctly and easily, i still need to find a way to add Height, but even with these 4 textures i get an amazing result
For the resolution i used 512 because that's what textures.com gives me, bit disapointed but i think due to the camera you can't see the blurryness
