What is causing this weird shadow with all my normal maps?

[FlorenceU]

Hello !

I’m learning how to do normal maps for 2D and did a few quick tests. For each test, I simply added the normal map as a secondary texture in the sprite editor.
The lighting is mostly coherent with each of the normal map I did, except for a weird shadow (the one circled in red on my first example). It follows the light when I’m moving it.
Things I tried :

• Rotate the light, change its inner/outer spot angle and the distance in the “normal maps section”.
• Changed it for another light like freeform light
• Tried in complete different scene with only one light and one asset

None of this changed anything, the shadow is still present and following the light.
What am I missing here ?

how does the normal map look like?

The normal map looks like this :

Normal map + original sprite

And here is another example :

Okay, I found the solution… If you have the same problem, check if your normal maps assets have the “Normal map” type, and not the “Sprite (2D and UI)” set by default !
