Since we use JME3 for all things related to textures, this problem cannot be 
fixed.

Can you explain a bit more detail (what cause this happned)? Or is there any 
way to avoid this error happened? It is understood that it might not be the 
code problem of open war, but that would be good if some clues can be revealed; 
so newbie like me can get around this issue. 

Thanks.

What is your graphics card? Can it handle OpenGL 2?

Hmm, I need to know where the error actually occurs. Did you start the program 
out of JMP? Edit the config.xml in the root so that it says "devMode=true" and 
give me the output of the whole log...

I think I find out the root cause. My graphic card driver is broken (It's 
intel/nvidia hybrid card). Once the graphic card driver is installed correctly, 
this issue (Image format 'DXT1' is unsupported by the video hardware) would go 
away.

Thanks for help.

Hello, someone pointed out this issue in JME3's forum, so I thought i would 
link the answer about it.

That's useful. Perhaps adding this to FAQ would help other users as well. My 
graphic card is hybrid and previously I was under the impression that the 
driver was installed correctly. After some other issues raised then I 
understand it may be the system uses Intel one instead of Nvidia's. 

Thanks again for help.
