Hey - I have been searching around the net for a few weeks off and on about the most common shadow map practices but it's actually kind of hard for me to get a firm grasp on the most common shadow map practices for deferred renderers with many lights (spot, point, direction).
I have working shadows - I have an FBO with an attached depth texture for every light (the FBO is contained in the light object). I was just wondering if this is the most common method (or if it is common at all) and was also wondering about the best techniques for point lights and direction lights. I know the cube map method and 6 spot light method for point lights - I know the method of a large resolution shadow map and far away position for the direction light.
I have read all the methods in gpu gems - its not really that I don't know methods I just wanted to here from people with experience using the different methods what they thought about them.
So - any experienced graphic programmers willing to share their deferred shader / multiple light shadow mapping methods?
