If I UNcheck all the double sided flags for all surfaces for all objects the openGL performance gain is huge.
It would be possible to make plugin which is setting/clearing double sided for all objects all surfaces, in one key press.
I'm pretty sure, like Sensei says, you wouldn't get any render speed advantage, as the same operations would have to be performed to make it render correctly.Wonder if it's possible to have LW render both sides of a poly even if the 'double sided' flag in the main surface editor is unchecked?
This is because having high density poly objects in layout with double sided surfaces slows down openGL performance
