The Stamping node inserts copies of a mask on a second mask. The node has two inputs: the base mask is linked to the top connector and the mask to use as the stamp to the second connector.
An optional mask connector allows a density mask to be used in the stamp. This option constrains the stamping to a part of the mask.
To add a Stamping node, right click in the Graph Editor and select Create Node > Mask Composition > Stamping.
Select the node to open its parameters:
This parameter defines the number of stamps in the mask.
A larger value adds more stamps.
This parameter defines the how the stamp is placed in the mask.
These parameters control the way the stamp can rotate. The default values let a complete 360° freedom of rotation, with a pace of 1°.
This parameter sets the percentage of scaling of the stamp and the repartition of the different sizes of stamps.
To set the repartition to the default values, right click and select Reset.
This parameter sets the non-uniform scaling along the horizontal and vertical axes.
This parameter sets the distribution of the stamp.
Instant Terra tries to respect the density input mask as much as possible, but if the number of stamps is too high, there will be cases where the position of the stamps will not respect the density mask. In this case, the number of stamps or the repulsion must be reduced.
|Number of stamps||Defines the number of stamps in the mask.|
|Stamping mode||Defines the how the stamp is placed in the mask.|
|Add||Adds the stamp to the mask..|
|Subtract||Subtracts the stamp from the mask.|
|Min||Similar to Subtract, but when several stamps are at the same location, the minimum value of these stamps is used at each vertex.|
|Max||Adds the stamp to the mask to create a raised landscape. When several stamps are at the same location, the maximum value of these stamps is used at each vertex.|
|Rotation||Sets the angle of rotation of the stamp.|
|Can rotate||When checked, the stamp can be rotated.|
|Minimum angle||Sets the minimum rotation angle down to -180°.|
|Maximum angle||Sets the maximum rotation angle up to 180°.|
|Increment||Sets the minimum angle of rotation.|
|Scale||Sets the percentage of scaling of the stamp and the repartition of the different sizes of stamps.|
|Can be scaled||When checked, the stamp can be scaled.|
|Minimum size||Sets the minimum allowed scale as a percentage of the stamp.|
|Maximum size||Sets the maximum allowed scale as a percentage of the stamp.|
|Repartition||Sets the distribution of large and small stamps using 10 vertical sliders corresponding to the different stamp sizes.|
|Non-uniform scale||Sets the non-uniform scaling along the horizontal and vertical axes.|
|Non-uniform scale allowed||When checked, the stamp can be scaled non-uniformly.|
|Maximum horizontal deformation||Sets the maximum horizontal deformation on a scale of 0 to 10.|
|Maximum vertical deformation||Sets the maximum vertical deformation on a scale of 0 to 10.|
|Placement||Sets the distribution of the stamp.|
|Try to avoid the edges||When checked, the stamp is constrained within the terrain. This may not be respected if the repulsion intensity is too high.|
|Repulsion||Intensity of the repulsion force between each stamp, from 0 (stamps can overlap) to 10 (maximum repulsion between each stamp). This may not be respected if the number of stamps is too high.|
|Seed||Value of the noise generation seed.|
