Since yesterday, I saw myself grey, but when I went to edit appareance I was fine. But then when I went out of it I was grey again. It was fixed when I took all my layers, and sometimes when I wear them again I'm not grey. The things are that I went to a sim, and everyone was grey, their meshes and prims were fine, but their avatars were completely grey, as if they had a grey skin. I'm in the lastest firestorm release so It is supposed that I can support SSA.
