UE4 – Bump Map

Posted on by Oded Maoz Erell

Software:
Unreal Engine 4.21

To use a ‘Bump Texture’ in UE4, or in more geeky terms, derive Normal data from a supplied height map, use the NormalFromHeightMap Node.

Notes:

  1. The height map textured is supplied via Texture Object node and not Texture Sample, and is connected to the NormalFromHeightMap‘s Height Map input.
  2. A numeric vale is connected to the NormalFromHeightMap‘s Normal Map Intensity input to control the intensity of the resulting Normals/Bump.
  3. UV coordinates for the bump map should be connected to the Coordinates input of the NormalFromHeightMap node.

Creating text height maps in photoshop

Photoshop CC 2017

When you need to create a 3D title that looks carved in stone by using a height map or normal map of the text design,
And you need to have the titles remain as live text in Photoshop so that you can easily make changes to the text if needed,
A simple way to make turn the text into a height map that would look carved or beveled inwards is to apply an inner glow effect and choose the “Precise”option in the “Technique” parameter of the effect.
