I wrote the beginning of a scene exporter plugin for 3D Studio MAX, but my plugin doesn''t appear in the list of format available in the EXPORT menu. Concerning the DllMain function, I''m sure the function is called by MAX because I have put a Message Box every time the function is called. Here''are the plugin code, if you could try to see what''s wrong:

  
HINSTANCE hInstance = NULL;
int controlsInit = FALSE;

extern "C" BOOL WINAPI DllMain(HINSTANCE hInstanceDLL, DWORD dwReason, LPVOID lpvReserved)
{
	hInstance = hInstanceDLL;

	if (!controlsInit)
	{
		controlsInit = TRUE;
		InitCustomControls(hInstance);	//Initialisation des contrôles de MAX

		InitCommonControls();			//Initialisation des contrôles de Windows

	}

	return TRUE;
}
