When I import my normal map for my tiles, it imports as a texture
Looks quite nice.
But when I change it’s type to ‘normal map’ it changes to this
I used Sprite Dlight to generate the normal map then photoshop to clean it up.
I’m using Unity 5.
[on a side note, I’m only able to add one tag in this post; adding a second overwrites the first]
Make sure that Convert From Grayscale is not checked. That’s probably the issue.
I fixed the problem by using the original texture as a normal map, without specifically setting it as a normal map first.
I think that unity thought I was trying to convert a diffuse texture into a normal map.
As per the poster below ‘Convert from Grayscale’ was likely checked’.
