How to use bump maps( not normal maps) in Unreal Engine?

[anonymous_user_6a619fcd]

Crazybump has decent controls for the normal map conversions, its probably one of the better options, compared to Photoshop or Unreal. Just got to play with the sliders. Although Allegorithmic or Quixel probably have the best modern tools for that kind of texture generation.

Do you mean substance designer or another software?
