We ran in to this same issue, but used the FinalDrawCallback to get around it. Just means if you have multiple post draws that you want to do, that you have to combine them in to one. Maybe writing an inherited callback for the finaldrawcallback that you can append multiple function calls to? Just an idea, not something I've done. We at one point just rewrote the OcclusionQueryNode's callback in to ours, but that ran in to all sorts of issue when we upgraded from 2.8.2 to 3.0.0.

Hi, Tell me I'm dumb but I'm kind of surprise that ones can't add several Camera postdraw callbacks. Is there a reason for it? Ex:I'm using osg::OcclusionQueryNodes in my scene, so when I set the PostDrawCallBack of the Camera during CullTraversal it replaces the one setted up by osg::OcclusionQueryNode cull traversal Thank you!
