I’m using the standard shader on my objects and I noticed that when I build for iOS using OpenGLES3, the normal map is displayed correctly (same as in the editor), but when I build using OpenGLES2, the normal map stop working (still fine in the editor, but not when running app on the device).
The quality settings for iOS is set to Fantastic, the rendering path is set to Forward.
I have a similar issue, when building with Graphic API to auto, my standard shaders are fine, when switched to openGLES2 I loose my normal and smoothness.
