It's taken me 4 times trying to upload a model. After more than 2 hours, it finally loaded. Once loaded, the WTVT indicated areas of concern. They small enough that I was going to let the Repair Tool fix it. But it appears not to be working.
Side note, since the new format now creates renders for each selected material, It appears to be slowing the entire system down. Uploading new models now seems to take 3 times longer. As if the system can't keep up.
Over complicated the basics. Tisk Tisk.
Rule #1, Don't fix it, if it ain't broken.
Rule #2. K.I.S.S. = Keep It Simple S........ (I won't finish that statement out of fear people would take it as an insult directed at them).
My system is an I-5 quad core, 32 gig ram, 1 gig GDDR5 video, Win 7, full updates, using chrome.
