Also keep in mind that these are *bitmasks*. The nodemask and the traversal mask are logically ANDed and check for a non-zero result. So if you set masks 1,2,3 on your nodes and then want to draw mask 1 it will actually draw nodes with masks 1 and 3. node mask 1 is 001 in binary, node mask 3 is 011 in binary, traversal mask 1 is 001 in binary, so 1 & 1 = 1 but also 3 & 1 = 1 /Ulrich _______________________________________________ osg-users mailing list osg-users@openscenegraph.net http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
