Filter Change
Overview
The Filter Change distribution makes a selection based on the effect a specified filter has on the terrain. This can be used to for example mask out the area affected by an erosion filter.
Parameters
Filter
References a filter to capture. You can simply drag a filter from your biomes filter list into this slot.
Level Step Strengths
Allows you to select at which level steps you want to capture the changes made by the filter.
Normalize Levels
Normalizes the strengths of all levels to the 0 to 1 range.
Combine Operation
Applies different operations when capturing the mask. Max results in all points added to the terrain being filtered, while min only takes the lower points.
This is not a correct representation for measuring sediment added in erosion, since each step of an erosion simulation erodes and adds sediment to the calculation, which can lead to a heavily eroded piece of terrain with some light sedimentation on top, which would lead to only the large erosion being visible (while there's also sedimentation present).
Level Power
Applies scaling to the different levels to scale their effect on the overall result.
Scaling
Increases/Decreases the strength of the effect.
