Hi Eduard, unfortunately I don't have any tips for the error you're getting. A couple months ago I tried getting OSG to use the DOM trunk code for its Collada support, and other than a few easily fixable compiler errors it worked fine. I didn't get any .so load errors. I was testing with Ubuntu

Hi Judia, What you are trying to do should work, but without the code for setting the different stateset to the appropriate nodes I can't say what exactly the problem is. The fact that you refer to NodeCParent looks suspect, you should apply directly to NodeC as NodeCParent is NodeA... Robert.

Hi Emilio, I think the best way to achieve what you want is to render your scene using two osg::Camera (two pass), first render your scene and then render the object you want to be in the first plane. Each camera have it's own near/far clip planes. Cheers, On Mon, Apr 14, 2008 at 3:06 PM, Emilio

Hi Emilio, the near clipping plane defines the border between things that are "in front" or "behind" you (resp. the camera). Since you cannot see what is behind you, I should expect that deactivating the clipping will not accomplish what you're looking for. If you want to see more of the ship
