you should call first activate and after this deactivate. If you have no
MaterialGroups in your scenegraph and your first chunk is always a
TextureChunk this code should work. Is your opengl context current?
Could be a frustum culling problem just disable it for the first frame.
renderAction->setFrustumCulling(false);
thanks, this solves the problem with initial texture loading. the
other method (window->validateAllGLObjects()) crashed sometimes.
i still have the issue that only wild tumbling of the scene brings
the framerate from 5fps up to ~60fps (test scene hase about 2.5
mio vertices, texture size is about 70mb after merge). i have a
GeForce 7800 GT and 2gb of system ram.
