I used PVRShaman to complie my PFX file. It said Warning: Extension GL\_OES\_texture\_3D not supported -\> error: reserved keyword 'sampler3D'. I used API OpenGLES 2 to complie (Tools -\> Preferences)  
  
this is my PFX file:  
[http://www.mediafire.com/?e6itmbilet3461o](http://www.mediafire.com/?e6itmbilet3461o)

Hi.  
  
  
  
  
  
Unfortunately at present SGX hardware does not support 3D textures and because the compilers bundled with our SDK are targeting SGX hardware, you’ll get the warning that the extension is not supported. Also because of this, sampler3D will not compile (neither will texture3D()).  
  
  
  
  
  
Furthermore, PVRShaman doesn’t support 3D textures while using the desktop OpenGL API either.
