This is the basic pfx shader code which works just fine in my windows emulator and also on iPhone device.  
  
  
  
On PVR Android, I am getting a error message  
  
"TEXTURE basetex missing matching UNIFORM in [EFFECT] on line 54"  
  
  
  
Can someone tell me what this problem is ????

Hi mkandula.  
  
  
  
  
  
In the latest SDK PFX semantics have been moved to tools code, so the semantic TEXTURE[0-n] should be used instead of your own FTEX\_IDX0 as PFX doesn’t know what this semantic is, hence the error.  
  
  
  
  
  
To correct your error change to the following code:

Code:

  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// GLOBALS UNIFORMS   
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;UNIFORM WVPMatrix&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; WORLDVIEWPROJECTION   
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;UNIFORM&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;sBaseTex&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TEXTURE0

Yes…I just got that figured out an hour ago…also I was using the older SDK for windows EMULATOR. With the newer SDK the bug is reproduced on the windows EMULATOR as well.  
  
  
  
  
  
Thanks for the reply !!
