MF HeightControls (Simple)

Unreal Master Height Function (Grey Scale Master) https://blueprintue.com/blueprint/1mcx7mzv/ If you want to make just use 3pointlevels into remapvaluerange & saturate it. My function removes the unnecessary stuff from 3pointlevels & saturates instead of clamping to make a cleaner easier to use function.

3pointlevels Params: Middle Value (0.5), Grey (0.5), White (1). 3pointlevels Constants: Black (0) Remap values Params: Input low ((1) I also use a 1- node & have switch with a bool to swap) 3pointlevels Constants: Input high (1), RemapTargetLow (-1), RemapTargetHigh (1)

When used for Height in Unreal Landscapes you will notice a major difference in how you can tune puddles from the landscape layer rather than the puddle layer: https://www.artstation.com/artwork/Jv4OXa

Disclaimer: If you want to use this for all greyscale textures: specular/roughness/AO. Don't! use 3pointlevels on it's own for AO. Roughness just multiply. Specular.... do whatever works. This is just tuned for height blends & to lesser extent displacement.
