[Opensg-users] passiveviewport incorrectly sorted

[Enrico Borrione]

Hi opensg users, i have a little question about a problem that has kept bugging me this afternoon: how do I sort the rendering order of different viewports? I explain my problem: I want to display a Shadow mapped scene inside an enclosed room. Since I can’t render all the geometry in the same viewport (I don’t want the ceiling to cast a shadow over the whole underling stuff), I decided to render the ceiling into a passive viewport and the rest of the room into a shadowmap viewport. If I keep shadows off, all seems fine. If I switch the shadows on, The ceiling is rendered on top of the room, actually erasing all the pixels it covers. Is there a way to be sure that the two viewports cooperates happily without so much z fighting? Thanks! enrico
