Strange artifacts at Original compression? #27

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Use an "Orcs Must Die! 2" character texture
2. Retexture it however you want, save it with DXT1 or DXT3/DXT5

What is the expected output? What do you see instead?
Get some strange "pixel noise" yet in the original, DXT1 was used and there was 
hardly any noise. Some black pixels turn into purple and rarely a very visible 
cyan.

What version of the product are you using? On what operating system?
Latest one (2.2.1) on Windows 7 Professional Edition 64-bit

Please provide any additional information below.
I am actually not VERY sure which compress the original used, but since the 
size is 682kb on the original and using DXT1 gives 682kb, I'm very sure it is 
DXT1. How can I confirm exactly?

Also, I do want to try the 3.0 version of this tool or the SVN Trunk, don't 
know how about the SVN one though, I do have TortoiseSVN.

Try out the new 3.0.0 release.  It should solve the compression artifacts 
issue.  Let me know if it helps!

Impressive! I tried it, and even though it doesn't keep the original quality 
even if I use DXT, it is VERY hard to see any graphical glitches or weird noise.

Thank you for this great update!

No problem!  Glad it is working for you now.  You won't see original quality as 
DXT is a lossy compression.
