I found the solution to my problem with stencil clipping by adding a line to sdlwindow.cpp file and recompiling Gambas3.
void SDLwindow::Show() { Uint32 myFlags = (SDL_ASYNCBLIT | SDL_DOUBLEBUF | SDL_OPENGL); SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 ); SDL_GL_SetAttribute( SDL_GL_STENCIL_SIZE, 8 ); <------------- This line fixed the problem ! And my project is properly working now. I've ported around 20 OpenGl tutorials already and you can find them on gambasforum.com. ---------------------------------------------------------------- Dzwonki MP3 na telefon. To sa prawdziwe hity!
