Nice renders!
Which of the render engines did you feel fitted best for the job?

So SU uses the graphics card when it renders views? (print and 2D saves)

I thought I read somewhere, where the question was why saving a png didn't match what was on the screen (in terms of anti-aliasing), that SU used software rendering when saving 2D graphics. Maybe that was an older version?

Would such a "thingy" sell well on eBay? I think I found some in the loft.

Try using Layout.

1. When setting the transparency to Nicer it tends to get the z-order of transparent objects wrong. The objects in the back overlaps objects in the front.
   I thought it was an issue with the graphics card on the computer I'm on. Because it's using an older IBM nVidia driver, and I can't use nVidia's drivers; they refuse to install. But when I export the scene as 2D the overlapping transparency also occur. And I was under the impression that when you export SU uses it's own software render?
   Faster or Medium setting seem to work fine however.

2. I got the Styles tool window open.
   I select a style, export as 2D.
   Then I try to select a new style. It looks like it's displaying the styles currently in the Model, but when I click nothing happens. There's also no tooltip when I hover over the styles. I have to use the dropdown-box and select In Model again before I can interact with the styles.
