If anyone is using a dual monitor set up on a MAC then you will dig this if you already dont know. If you want to edit on dual monitor set up then simply split your 3-D view into two then expand the bottom right corner over until you are in both monitors then move all your buttons to the bottom right on the second monitor and there it is dual editing in Blender. Most of you probably knew that, but its more for the new guys like me who are in Blender "everything is new to me " mode.
The second cool thing is if you want to render two camera shots of different angles at the same time then here is what you do since Blender does not allow it in itself.
1 - Download Blender 2.4 the latest as your primary (Most of us have it already)
2 - Download Blender 2.37a and place it in the same applications folder as the 2.4, but NOT inthe same 2.4 folder, just beside it on your HD.
3 - Open the 2.4 and your project and select the first camera and hit render as you wish. Now while its rendering go ahead and open Blender 2.37a
4- Open your project in 2.37a and rename it with a (2) after it
5- Now create your second camera animation and hit render
Now you are getting two camera shots at once! If your MAC can handle the processing that is.
But no more waiting for one shot to be done to go to the next.
