If the **Min** is -1 and the **Max** is 3, then the base is at the Texture value 0.25. This uses the full range of the heightmap.<br />&#8226; **Amplitude**: Allows you to manually set the amplitude and base position of the heightmap. This uses the full range of the heightmap. In this mode, **Amplitude** sets the range of values and **Base** defines how far through the range the zero value (base) is. For example, if **Amplitude** is 100 and **Base** is 0.5 (the default value), the minimum value is -50 and the maximum value if 50. If you then set **Base** to 0, the minimum value becomes 0 and the maximum value becomes 100. |

 | **Emission Multiply with Base** | Enable the checkbox to make HDRP use the base color of the Material when it calculates the final color of the emission. When enabled, HDRP multiplies the emission color by the base color to calculate the final emission color. |
