Hi Robert -- I'm seeing an issue where, as the viewpoint approaches the terrain, textures surrounding a high-res inset disappear. This is with very current VPB and OSG running on Mac OS X with a GeForce 8800 card. ss0.jpg shows the scene just before the issue occurs. As I move the viewpoint forward (closer to the terrain), I see the image in ss1.jpg. I also get several instances of the following error in the console: Warning: detected OpenGL error 'invalid enumerant' after RenderBin::draw(,) There is strong correlation between this error and the appearance of segments of the database rendered with a missing texture image. I've attached the mkdb.sh script I used to generate the database. Do you have any hints on what might be going on here? This is not the first time I've seen this issue, so I don't think it's new. I've tried changing the value of OSG_DATABASE_PAGER_DRAWABLE but this has no effect on the issue. I'll try rendering the DB on a Windows box and see if I get the same results. Thanks for any help.
