Ok then, trying to make sense of this whole model effects loading code... In `modellib.cxx' the `loadFile' and `loadModel' functions, which check the file extensions for a `.ac' file and if so sets a flag for instantiation of effects. This flags is only checked in the

Well, just adding the .osgb extension in modellib.cxx is not enough to trigger effect loading for it...no surprise I guess that some extra processing is needed in other places as well. Hmm, having to reverse engineer a bunch of undocumented model and effects code in simgear, as well as also

Hi all, I'm experimenting with various model file formats and the effects system and have some questions/comments. First I found that if you have a file 'model.ac', but also have a file 'model.osg', flightgear always loads the .osg version despite me explicitly requesting the '.ac' in the models
