Re: [osg-users] Problems with RTT, Shadowmaps and Callbacks
Hi Martin, regarding the callback issue on slave cameras please check this thread: http://lists.openscenegraph.org/pipermail/osg-users-openscenegraph.org/2008-November/019337.html Cheers, Ricky On Tue, Oct 25, 2011 at 16:21, Wojciech Lewandowski lewandow...@ai.com.plwrote: Hi, Martin I am assuming you are complaining about limitiation of techniques derived from ViewDependentShadowTechnique.

But my problem is, all my callback function doesn't work now. The only work with nested cameras. It is a big dilemma, isn't it? What can I do? Is there a typical solution for this problem?
