I’d love to be able to create undulation in large sections of ground, such as this pebble driveway. I struggle to find textures that allow this via the bump. So either this could be a texture parameter, or you could make one of the basic plane models with a ripple parameter and scale so I could place that on top of my driveway and change the settings to suit what I need.
As you can see the result of the gravel hitting the kerb is a completely perfectly straight line, but of course that wouldnt be the case, and i’ll have to photoshop it.
