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.
