This update to my Mental Ray texture baking script streamlines some of the code and adds some minor features.
You can now type in the Output Directory with less fuss – the script will parse forward and backward slashes – and will create the necessary ‘lightMap’ folder if it is not present.
Added a button to open the selected (from the dropdown list) bake set in the attribute editor.
Created a handy shelf icon.
