    Changing CG shader parameters from another thread.


      I'm developing a graphics engine in which graphics and game logic are executed in separate threads. CG is used as shader language.

      When I try to update shader parameters from the logic thread (during scene graph evaluation) program crashes on CgSetParameter*() functions. OpenGL context was created in the rendering thread.

      When I changed the engine to be single-threaded everything works fine.

      Multi-threaded version works fine on NVIDIA cards.

      So my question is: is it possible to change shader parameters from thread that hasn't created OpenGL context?
