| var | `Component Size`3) Landscape | `SectionSizeOptions` | The number of quads in each section. Should match the settings from the referenced Landscape above, if any. |
| var | `Sections X`3) Landscape | `int` | Number of sections in the X direction. |
| var | `Sections Y`3) Landscape | `int` | Number of sections in the Y direction. |
| var | `Overall Resolution`3) Landscape | `Vector2D` | Overall resolution calculated based on Section size and Section Counts. This gives the option to match existing landscapes. |
| var | `Show Procedural Impact`3) Landscape | `bool` | When specifying a Landscape above, this flag allows all Landmass modifications to be Toggled. |
| var | `Show Water`1) Real Time Simulation | `bool` | Toggles the optional display of debug water on the Mesh Preview Material. If the preview material is overridden, the material must include the necessary water preview functions. |
| var | `Velocity Debug Brightness`1) Real Time Simulation | `float` | When the above 'Show Water' flag is enabled, this value allows tweaking of the displayed velocity brightness. It is purely for debug visualization feature. |
| var | `Button Press Iterations`4) Erosion | `int` | How many iterations to perform when pressing the 'Perform Iterations' button. |

| var | `Delta T`4) Erosion | `float` | The amount of time per frame. Can be thought of as 1 / fps of sim. The default of 0.016 is set for 60fps (ie enter 1/60 to get that value). Larger values can lead to instability. The Free Particles method is the most flexible with larger deltaT. |
| var | `Rain Amount`4) Erosion | `float` | The amount of water height to add to each terrain vertex every iteration. |

| var | `Layer Stack`6) Brush Layer Stack | `BP_LandmassBrush[]` | — |
| var | `Weightmaps`3) Landscape\|Weightmap Setup | `Map<name, RenderTargetChannels>` | This lets you add Weightmaps that can be written to by brushes. Each weightmap will be RGBA and include 4 channels. Be sure to name them and place TextureSampleParameter nodes in your Preview material with matching names. |

| var | `Scatter Particle MID`7) Debug\|MIDs | `MaterialInstanceDynamic` | — |

| var | `Cached Invert`7) Debug\|Cached Values | `bool` | — |
| var | `Smooth Slopes Less Than`4) Erosion | `float` | When > 0, acts as a filter for smoothing neighboring Heightmap texels. |
| var | `Velocity Damping`4) Erosion | `float` | This is an Exponential Damping term that is used to prevent fluid velocities from ever growing. It is applied exponenetially so that the damping result is time step independent. |
| var | `Prep RTfor LSMID`7) Debug\|MIDs | `MaterialInstanceDynamic` | — |
| var | `Octaves`2) Generation | `int` | The number of noise octaves to use. More octaves give more detail, but add cost to the GPU for re-rendering the stack. |
| var | `Persistence`2) Generation | `float` | Persistence is how much the noise amplitude is scaled down for each new octave. The default is 0.5 which means each octave gets half as intense. Lower values will give smoother terrain. |

| var | `Erosion Weightmap Effects`4) Erosion | `ErodeWeightmap[]` | This is an Exponential Damping term that is used to prevent fluid velocities from ever growing. It is applied exponenetially so that the damping result is time step independent. |
| var | `Max Iterations`7) Debug | `int` | When above 0, limits iterations. Useful for comparison various settings with the same number of iterations. |
| var | `Combine Landscape Noise Water MID`7) Debug\|MIDs | `MaterialInstanceDynamic` | — |
| var | `Total Z Range Kilometers`3) Landscape | `float` | By default, the max Z range is 0.65536 kilometers or 65536 centimeters. Since height is stored as an integer with a range from 0 to 65536, this allows one centimeter precision. Higher ranges are possible by sacraficing some precision. Note that the range is split in half so the default 65536 cm is split into -32k to +32k range. This means a 'flat' default landscape starts at the halfway point so if you intend to paint very steep mountains, you may want to offset downwards towards the bottom floor first. |
| var | `Landscape Actor Z Scale`3) Landscape | `float` | This is the Z scale a Landscape actor needs to be set to in order to have a matching Z range. |

| var | `Cached Position`7) Debug\|Cached Values | `Vector` | — |
| var | `Force Power Of 2`3) Landscape\|Overrides | `bool` | Useful when using this to create textures as displacements. This will round up to the next size power of 2, enabling static textures to be created. Ie 2041 becomes 2048. Some minor preview precision will be lost since the grid will not be adjusted to account for this. |
