[osg-users] Missing shader in OverlayNode.cpp

Hi Robert, I looked over the OverlayNode implementation and recognized that it seems that a shader is missing at line 1094 in OverlayNode.cpp (latest SVN version), when the overlay perspective vertex shader can't be found at shaders/overlay_perspective_main.vert. At all other shaders there is

[osg-users] 'loosing' textures?

Hi everyone, Since I have upgraded to OSG 2.0 (a few months ago) I seem to 'loose' textures on loaded models. It is not very clear to me what happens, and it is not easy to describe. At the moment I was wondering if someone has a hint or so. Thanks a lot, Raymond
