Hi there rheyzhel ,
Cloudy avatars can happen due to a lot of things like a bad or wireless internet connecton. ( To name just 1 )
What you can do is try to clear your cache Viewer 2 ... "me" tab ( left top corner ) > preference > setup > reset cache ... than press ok to confirm and log out of SL and than log back in again . ( mind you it can take a while to log back in because of the clearing cache and when your are back in SL everything will rezz slow ) With another viewer its .... edit > preference > network > clear cache ( again relog )
If this doesn't help you have also the option to reset your avatar , my experience is that most times this helps the best. For V2 do the following ... press Cntrl+Alt+q ( this will show you a develop tab at the left top of your screen , if its already there dont do the cntl+alt+q ) develop tab > avatar > character test > test male ( or female ) . With other viewers Cntrl+Alt+d ( the letter ) ( this will show you an advanced tab at the left top of your screen ) advanced > character > charactertest > test male ( or female )
When you do the character test your avatar will be set to default so make a note before on what you are wearing so its not to hard to find it back an putting on again.
I hope this will help for you , if you are inworld you can also seek help at places like Help People Island or NCI. Good luck on it
Cheers Taka
