Iam gaving the same issue, has of yesterday. I have the LATEST firestorm viewer, ABLE to support the new server side baking changes, and now after a year of SL, im seeing everyone grey, when this new viewer is suppose to correct this. Did clean install, removed caches, tryed Official SL viewer, all remains the same.Restarted Router, Tryed stuff like removing HTTP textures, followed and read steps in articles such as this http://blog.nalates.net/2013/08/23/second-lifes-new-bake-fail/ And seems all blog posts i read, such as this one, just provide answers, such as u need the latest SL viewer....when its stated that THE LATEST viewer is in USE already. So if anyone can provide a real answer, to why , despite of already being using the latest SL viewers, that should solve and be compatible with server side baking, despite performing complete clean install, me,having a good connection, never had this problem for the past year, im having it now. and why now i see others grey. including my own. never had this terrible issue until yesterday ( 5th of June, 2014.)
thank you
