Hi,  
  
  
  
  
  
I just upgraded my command line utilities from the following version:  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PVRTexTool Version 3.20  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SDK Build: 2.08.28.0607  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PVRTC Version 1.106.0.0  
  
  
To the version:  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PVRTexTool Version 3.23  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SDK Build: 2.09.29.0677  
  
  
  
  
  
The 3.23 version produce lot of artefacts on semi-transparents pixels. Those artefacts were not present with the 3.20 version.  
  
  
  
  
  
Also, it seems those artefact aren’t present with the GUI version.  
  
  
  
  
  
Here is the command line options i use:  
  
  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;PVRTexTool.exe -fOGLPVRTC4 -o"outpu.pvr" -q5 -yflip0 -i"input.png";  
  
  
  
  
  
  
  
  
Is it a known bug? Or a misuse?  
  
  
  
  
  
Best regards,  
  
  
Greg.

Hi Greg,  
  
For semi-transparent textures there should be no differences with that version of PVRTexTool - could you send me a copy of your texture to[devtech@imgtec.com](mailto:devtech@imgtec.com)? If I can have a look at it I should be able to figure out what’s going on.  
  
Fully/near-fully transparent pixels may show issues, as the new compressor will automatically bleed the texture into these regions as an optimisation step, but semi-transparent pixels should remain unaffected.   
  
Thanks,  
  
Tobias
