Hi,





I just upgraded my command line utilities from the following version:


               PVRTexTool Version 3.20


               SDK Build: 2.08.28.0607


               PVRTC Version 1.106.0.0


To the version:


               PVRTexTool Version 3.23


               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:


     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? 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
