Hi, Daniel You found the solution? I try to make similarity of game with OSG, but also it isn't clear to me how to make dynamic terrain. Vertex Displacement through a shader looks very well, but there is a problem - vertices heights don't remain in geode, they is generated in the course of work

Re: [osg-users] Dynamic terrains, DatabasePager + PagedLODs
