Really solid work, I was surprised to see how complete this is, especially compared to Blender. I need to render some scenes soon, importing existing OBJ's and adding new materials. I was going to be using Blender, I'll first give clara.io a try!
One question, sent a ticket already but wouldn't mind an HN bump... I couldn't get 'Render > Render Current Pass' menu option to show? Kinda miss that big green "render now" button.
