[osg-users] txp lod problem: switching in cycles

Hello, I have a heavy application which uses osg viewer and a TXP terrain. After some time the application is running, LOD level of the terrain starts being switched higher and lower all the time in cycles, so one second I have trees and building being displayed and one second later - they

Hello Andrea, I didn't go through every line of code of your example, as it is far from being minimal. Maybe I'll dig into it later on - but it would be best if you'd assemble a minimal compileable example. Also I'd suggest trying to do some minimal debugging, i.e. don't try to do everything
