Creating text height maps in photoshop

Software:
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.
