I’m new to shaders and I don’t even know where to start from.  
  
I’ve implemented a Specular map, but I’m not sure if I’ve implemented it correctly.  
  
Are there any examples in PVRShaman of it combined with a diffuse map?  
  
  
  
Thanks,  
  
Cosmin

Hello  
  
  
  
The defered shadding sample is probably the best one and it use what your are referring.  
  
it s very well coded and it can be use as a starter from my point of view  
  
Kind regards
