The Snow node applies a snow color map to a terrain at locations defined by parameters.
This node does not modify the terrain.
The node has one input: a terrain with or without a color map. If the terrain input does not have a color map, a neutral color ramp is applied and is visible in places not covered by snow.
The node has two outputs: the unmodified terrain with an updated color map and the snow mask.
To add a Snow node, right-click in the Graph Editor and select Create Node > Colorize > Snow.
Select the node to open its parameters:
This parameter does not apply to the north faces, which are always 100% covered by snow: only the lowest altitude parameter is applied to the north faces.
Tip: Place it after a Colorize or Advanced Colorize node to achieve the desired color for rocks and sediments. The results are interesting if we have sedimental smoothing and rock erosion: they will smooth the ground and add sediment at the bottom of the slopes to give a snow accumulation effect.
With sedimental smoothing and rock erosion:Without:
|Snow color||Sets the snow color.|
|Lowest altitude||Expressed as percentage of the maximum height. Below this value, the color map remains unchanged.|
|Max slope||The angle beyond which the snow does not settle.|
|Depression filling||Propagates the snow onto the concave parts of the terrain..|
