Hi Art and All, by checking the glow example of osgPPU I was wondering if it's possible to render the glow (but in general any special fx ) camera AFTER the main one. As a child unit waits for all parent to be drawn it should be possible, isn't it?
The reason I'm asking is that I don't understand how the glow camera can perform the depth test against the main depth_buffer, as it is rendered *before *the main one. Is the depth_buffer of the main camera coming from the previous frame? Thanks, Ricky
