Blob Generator draws circles on the map map in places where objects are located. It can be used for painting maps under objects.
Blob Generator could be also used for creating special masks, for example, a grass mask. to avoid grass growing under the objects:
Objects (mandatory): objects that would be the centers of the flat areas.
Canvas: the map to stamp blobs. If not specified then blank map will be used.
Mask: the map that controls generator's intensity.
Input canvas with object stamps.
Radius: the size of the blob stamps.
Radius: 5, 10, 20
Size Factor: multiplies the changes applied by this generator depending on the initial object size. For example, if the object’s size is 2 then all of the adjustment values will be doubled if the factor is equal to 1. This is useful for proportional object changes: if the object should be lowered to half of it’s height, for instance. When the value is 0 all of the objects are adjusted the same regardless of their size.
Safe Borders: if not equal to zero generator effect will be fading down near the chunk border to prevent seams between chunks. Property value determines the fade length in world units.
Fallof: flatten intensity depending on the distance from the object center. Left of the curve is periphery, right is the object center. Think of it like a flat area profile.
Noise: if not zero some noise amount is added to the fallof to prevent unnatural clear slopes look. "A" property sets the amount of the noise, and "S" - the noise size.
