Normal map in dark

How to make them see the normalmap in the dark game, because if the light is dark, the normalmap is don’t see on the objects. I need this because I create a horror game, and the light is verry dark, like Slenderman.

I’m sorry if I don’t speak English cursiv! :slight_smile:

Thancks!

two options:

A. you would have to add a light source.

B. make the material self-illuminated.
