Snow

Currently, this feature is used in SnowRunner only.

The Geometry > Snow brush allows you to control the depth of snow.

This brush can only be used on the snow terrain layer, after painting it with the snow_layer layer of the corresponding PBR material (see Assigning PBR Materials to Terrain).

You can paint using this brush if there is at least a little layer of snow terrain in the painted area. For example, if 0 amount of the snow is painted on the layer, then there will be no deep snow; however, if the weight of the snow on the snow layer is 50%, then deep snow can be painted. This is done so to avoid sharp "steps" of the deep snow (since on the map of the deep snow 1 pixel equals to 50 cm).

As with mud, after painting with the depth of the snow, a region with vertical lines with horizontal marks will appear on the terrain. The more horizontal marks are displayed on the vertical line, the deeper the snow is.

IMPORTANT: If there is solid ground under the snow and there is no mud, the car will not sink in the snow for more than half of a wheel. If the snow is deeper than 1 horizontal mark (see screenshot above) and there is a hidden mud (mud of the "Extrudes" type) under the snow, the car will sink deeper in the snow and will bury itself in the snow below the level of the wheels.

Properties:

  • Depth - sets the depth of snow (similarly to Mud).

  • Flatten - flattens snow depth.

  • Smooth - smooths transitions between sections of snow with different depths.

By enabling the Update material option in the Brush window, you can add both the depth of the snow and the snow_layer itself, simultaneously.

NOTE: If you are creating a large level and are working with snow (painting depth or working with a material with the snow_layer), then we recommend you to disable the auto rebuild of the terrain. Otherwise, the auto rebuild and/or any operation with the material will take a long time.

To view the final result of the performed changes, you need to rebuild the scene. To do this, right-click the scene window and select Rebuild Terrain or Rebuild Visible / Selection (to rebuild only visible or selected areas).

After painting with the depth of snow - the system will mark this level as snowy. And, only after that, the soft_snow and crust_snow layers can be applied (see Material Properties for details). They will be available only after performing Rebuild Terrain also. The Procedural snow coverage parameter of the Terrain (see Terrain Properties) also works only for snowy levels.
