The was really odd, i don't think I've seen that before. All other web pages, forum and KeyShot, load just fine. I just checked again and now it looks normal, except I had to adjust the zoom factor a bit.
And obviously this forum needs a direct link to the Alibre home page. I don't understand why this hasn't been done yet. Usually, clicking on the Alibre symbol activates the link. That's my point. A bit off topic.
Those are some features we are toying around with, though I can say most of the texturing stuff probably won't be in v22 as we are working on some more fundamental things. You saw them because they were hidden on the v21 page via stylesheets, and those were broken. In any case, we're finalizing v22 now.
