avi is a few triangles [prims?] not a body

[ZoltanKodaly]

Other avis can see me as normal, but I see my avi as mostly transparent, with triangles for shoulders belly legs; most of face is missing.

Hi,

If others can see you as a complete avatar, it is possible that your graphics card or memory is not sufficcent.

I would suggest taking a photograph of your avatar.  If it looks like triangles, I'd say it's your system.  If the photo appears normal, it may just be a matter of freeing up some memory.  Good Luck
