Doh. Looks like I solved this one already by setting the switch-in distances on my filenames to infinity. Guess I should have thought of that before. Thanks anyway.... - Terry

I'll be sure you get you a copy when the loader is ready for stress-testing. Now I have a little logic question for anyone who has done terrain paging. I want terrain tiles at level 1 to be replaced by multiple tiles level 2 simultaneously. But if each tile has its own LOD center then level 2 tiles pop in at different times as you approach them, and this causes holes to appear in the terrain. I can fix this problem between levels 1 and 2 by setting the same center on all these tiles. However, this center is inappropriate for the level 3 children of a level 2 tile. What I really need is for each tile to have have a separate switch-in center and switch-out center. My scene graph is set up in units that look like this. A PagedLOD has multiple child PagedLODs and one filename representing the tile at that level. Each of those child PagedLODs contains multiple PagedLODs and a filename just like this one. PagedLOD --- PagedLOD PagedLOD PagedLOD PagedLOD FileName Does this explanation of my problem make sense? Is there a better way to set up the graph to solve this problem? - Terry > Hi Terry, > > I'd be interested in supporting your effort to create a (partial) MetaFlight > loader in any way that I can.
