I figured it out. Turns out I needed to set the source format of my render texture to GL_RGBA. Its interesting because if I had set the texture's internal format to GL_RGBA it would have worked because when the source format is not set the osg::Texture2D class uses the internal format as the pixel format in the call to glTexImage2D, which is valid for an internal format of GL_RGBA, but not for GL_RGBA8 because the former can be used as both an internal format and a pixel format, but the latter can not.
I've see this issue with other using the incorrect usage of GL_RGBA8 (and GL_RGBA16) in other areas within the osg::Texture2D class - see my thread: http://forum.openscenegraph.org/viewtopic.php?t=9879 Alex[/url] ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45550#45550 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
