Shader Mobile/Bumped Specular not affected by Directional Light

Questions & Answers
1

Hello everyone,

I’m working on a 3D project on mobile (Android) and I have issues with build-in shaders.

  • I want a bumped Specular to be hit by the only one directional light in the scene (at the moment, the mesh simply goes black)
  • Even the bumped Specular (1 directional Light) shader gives black objects that can barely be affected by point lights

Those shaders are under /Mobile category. What else could I do ? I need my object to be affected by directional and has a normal map on it.

I’m using Unity 5.2.3f1. Thanks for your help !

Edit : Notice that the two issues were seen on my Android device (Samsung Galaxy Note III)

I solved my problem.

There were no tangents for the mesh I imported, so I set “Calculate Tangents” in my model import settings and now the light hit them right.

For further information :

Note : It happened that this problem didn’t occure on every android plateform. I have a collegue using an Asus Mobile tablet and it worked well - same model, same lighting.

Hope it helped !
