My character's normal map appears to not have an effect

I imported a character model that I made into the game, both the base texture and the normal map seem to have successfully loaded in. However, the normal map doesn’t appear to be working as the character lacks detail it’s supposed to have.

Here’s how the character should look like (screenshot from Blender):

Here’s how it looks like in game:

This is how the metadata materials look like:

It’s not giving any errors or anything, so I’m not really seeing why it isn’t working. I’m pretty new to 3d stuff, especially the technical side, so I wonder if I’m missing something to make the normal map “activate”.

Any advice would be greatly appreciated!

Try adding some specular value to it and see if it shows up then. Sometimes normal maps are so shallow that they don’t show up well without that.

Also make sure your maps are named as they should be and use the same file type. (PNG with PNG, TGA with TGA, etc.)

Unfortunately, increasing the specular value doesn’t seem to work. The file name for the PNG should be correct (Material_Normal.png), otherwise it wouldn’t show up in the metadata, right?

I’ve imported the model both with and without the normal map, and it looks identical either way in the game, which is quite confusing.
