Hi, Thanks. I have managed to get it to work by writing out a dummy value to the end of the terrain tile record and then calling the TileLoadedCallback when I read the value back in but as I said, this is a very ugly hack.
My question now is, at this stage, is it a good idea to rely on the TileLoadedCallback mechanism within the current osgTerrain design? I think I can implement what I need without using it if it looks like this may disappear in future versions (given it is currently broken with the new serializers). If it is likely that the feature will stay I will just fall back to writing out .ive databases for now until a good solution can be implemented (I need to generate some new databases very soon for some demos). Thanks for the input.

Hopefully Wang Rui will have some thoughts on how to do this. My guess is that the design at present isn't set up to do stuff like this, but is possible to customize the process a bit so hopefully it won't be too difficult. Robert.
