In my code,

I put following in the ReleaseView()
  

&nbsp;&nbsp;&nbsp; /\* Release the Print3D textures and windows \*/&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; gsMyPrint3D.DeleteAllWindows();&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; gsMyPrint3D.ReleaseTextures(); 
  

&nbsp;
  

I put following in the InitView()
  

&nbsp;&nbsp;&nbsp; /\* Init Print3D to display text on screen \*/&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; if(!gsMyPrint3D.SetTextures(0,PVRShellGet(prefWidth),PVRShellGet(prefHeight)))&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; {&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PVRShellSet(prefExitMessage, "ERROR: Failed to initialise Print3Dn");&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return false;&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; }
  

&nbsp;
  

I put following in the RenderScene() (I also used FragShader and&nbsp;vertshader on a special 3D object in the current window before print out text)
  

&nbsp;&nbsp;&nbsp; /\* Print text on screen \*/&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; gsMyPrint3D.DisplayDefaultTitle("Test", "First test&nbsp;with PVRTC", ePVRTPrint3DLogoIMG);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;  
&nbsp;&nbsp;&nbsp; /\* Flush all Print3D commands \*/&nbsp;&nbsp;   
&nbsp;&nbsp;&nbsp; gsMyPrint3D.Flush(); 
  

&nbsp;
  

But my program always exit with "ERROR: Failed to initialise Print3Dn". In other word, the SetTextures function always return PVR\_FAIL.
  

Could anyone give me a hint why the SetTextures is not working correctly?
  

&nbsp;
  

THank you very much!

Hi,
  

&nbsp;
  

Your line for SetTextures should be
  

&nbsp;
  

Code:

if(gsMyPrint3D.SetTextures(0,PVRShellGet(prefWidth),PVRShellGet(prefHeight)) != PVR\_SUCCESS)&nbsp;&nbsp;

  

&nbsp;
  

instead of
  

&nbsp;
  

Code:

if(!gsMyPrint3D.SetTextures(0,PVRShellGet(prefWidth),PVRShellGet(prefHeight)))&nbsp;&nbsp;

  

&nbsp;
  

as SetTextures returns&nbsp;zero (PVR\_SUCCESS) on success and not on failure.
  

&nbsp;
  

Thanks,
  

&nbsp;
