Normal Maps Import problem on Mobile App

Questions & Answers
1

Hello everyone,

I want to create a mobile game. I have imported in Unity my mesh and its textures (diffuse map and normal map). The textures are 2048x2048 .png files and I use the “Mobile/Bumped Diffuse” shader on my material.

Everything was fine until I compiled my Android application. After the compilation, my imported normal map suddenly was terribly distorted, as you can see on the following picture (on the left, the .png normal map ; on the right, the imported normal map in Unity) :

Now, even if I try to import it again from scratch, the same distorsions appear on my normal map. Do you know why and how I can fix that ?

Thank you very much for your help !

Click it in editor. In inspector set Aniso to 0 and format to True Colour making sure that it is set to be a normal map.

See if that makes a difference. You may need to re-import it for this to work.

I found the solution. It was the compression of the normal map (by default RGBA 16bits ; I changed it to RGB 32 bits) that caused the problem.
