Hi Robert, I noticed that when the PerContextProgram is first created, it iterates through the existing shaders and calls "attachShader" on them. This is never called for shaders that are added at runtime. Also, shaders that are removed will never have "detachShader" called on them. Could any of this be related to my problem?

Hi Robert, I'm not sure exactly what to test. I was able to verify the following by printing out debug messages: - The program is being dirtied - The shader is being compiled - The program is being linked - The program is being applied to osg::State Does osg::State do any sort of caching of Programs that could be preventing it from refreshing? -Farshid On 9/8/06, Robert Osfield <[EMAIL PROTECTED]> wrote: > Hi Farshid, > > What you are doing should work, I haven't tried it personally though... > > There are dirty mechanism in Program that should detect this change, so I'd > recommend that you just put some debugging code into osg::Program and see > what happens. > > Robert. > > > On 9/8/06, Farshid Lashkari <[EMAIL PROTECTED]> wrote: > > > Hi, > > Should it be possible to change the osg::Shader of an osg::Program at > runtime?
