Hi Guys
I was having trouble getting the custom ui to find the lighting presets plugin
I have downloaded the lightingoptions.zip and copied it into the commands folder
it runs from this script on a key script: /* Opens Lighting Options Dialog */ moi.ui.createDialog( 'moi://ui/LightingOptions.htm' );

and would you believe it once I used the above script the custom button works
So problem solved
