Yay! (Trawling through the counting thread for all the gems does get quite tedious
Okay so covering the Ubuntu Cubes
(Which, yes is just a load of coloured cubes, nothing that special except that it eats ram for breakfast.)
The scene was made in Cinema 4d 10 (iirc) which had used older and much outdated algorithms to calculate the scenes global illumination
(GI), it also let you use the default light to render scenes under GI. However, both of these factors have now changed since v11.
This means that to render the scene now you need to place a light manually, (say x: -500, y: 2500, z: -2000) and then (since it auto converts the GI setup to the new version) tone down the GI settings (Well you could leave them be if you wanted but I've found you can get away with much lower settings, and thus a quicker render, without too much fuglyness - turn them back up if you notice any though)
To do this:
Click the button to the left of the Cube picture (This is the Render settings window, you'll visit this lots!).
Click Global illumination.
On the Irradiance cache tab you can probably get away with lower settings (I quite often use the lowest which don't look to bad for most things).
From top to bottom: Low, preview, Least Squares (aka don't need to touch), Minimal, should be greyed out, None.
BTW Ted, did I ever give you my Pens
