Zoen Repine

I just recently began having this ussie ever since I upgraded from a 40 GB hard drive to a 320 GB hard drive. I did not have this issue on the older 40 GB hard drive. On two of my avatars and on both of the test avatars, the basic up-to-date Second Life viewer renders the neck invisible on these avatars. On top of that, sometimes their waistline and their ankles are rendered invisible as well. I've tried changing skins, editing shape, trying on different inventory items, clearing cache, rebaking, and even just recently did a full fresh reinstall of Second Life, yet this issue remains persistent. I'm out of ideas on what to do, so I am turning here to see if someone else can help me figure out what's going on. Screenshots to highlight and display the invisible sections I'm talking about on the two main avatars I use are linked below. The same issues show up on the test avatars. http://img.photobucket.com/albums/v305/The_Bombers/slneckissue_001.png http://img.photobucket.com/albums/v305/The_Bombers/slissues2_001.png
