I have made a sky sphere for my environment. The sphere is mapped with a panoramic sky map of high quality 4096*1024. I update its location to always be that of my camera and turn culling off.
This works but the image quality is degraded, there is a horrible stepping. My color depth is set to 32bit. Is this a texture compression problem? Any suggestions on how to fix this?
Here is the picture:
It could be many things. Try taking a look at some of the suggestions here: http://www.jmonkeyengine.com/jmeforum/index.php?topic=4747.0
But a few quick things (some of which are in that thread):
Check to see if S3TC is off, if not, turn it off.
Turn off mip-mapping (in the thread)
Turn on anti-aliasing (in the thread)
Between one or all of those you should notice a pretty big difference
Thankyou Christius,
turning of S3tc did the trick.
For those with a similar problem, you can do it too, send no money now!
