Most people who use Maya, Nuke, etc will disable UAC because of batch render issues. In Windows 8.1/10/Server it will give you some errors where you cannot run native Windows app with the error "App can't open with built in administrator account".

When you make title elements or other motion graphic elements for Premiere you often end up with grey edges because most of us render out these elements als PREMULT. But, if you render it as UNPREMULT then the edges become clean. The RGB channels will look weird, but when placed with the Alpha it looks good.

Press '7' do you see the black objects? Check... If this is the case set the Render Lights to 'Default' instead of 'All'

To clean up yout namespaces after importing/referencing objects try this:

After your objects are imported paste the following line into the script editor –

namespace -mv "insert_namespace_here" ":" -force;

Replace insert_namespace_here with the namespace of your imported objects. ie for an object that is named part1:Cylinder02 use the following –

namespace -mv "part1" ":" -force;
