Hi, When you are in the Hebridan system for this mission you'll want to destroy Baal's Mothership, and all the Goa'uld and Besarian ships including all the Besarian fighters. I've tested it twice today and everything went fine.
Make sure the following missions (jobs) are completed and do not say failed:
Destroy System Lord Baal's Mothership. After all Goa'uld and Besarian ships are destroyed go to the planet Hebridan. (failure is not an option-repeat mission if says failed)
and
Destroy all Goa'uld & Besarian Ships in the Hebridan system. When all enemies including Baal's ship are destroyed, go to the planet Hebridan (Failure is not an option-Repeat if Failed)
After completing both these missions you'll need to go to the planet Hebridan and Enter the Site Center to activate the next mission.
I've included a picture attachment of what this should look like when you press V in-game.
Possible reason(s) for the next mission not occuring:
(1) still have Besarian fighter(s) that need to be destroyed to complete one of the jobs.
(2) maybe left the Besarian system. Sometimes when a player leaves a system for awhile then the ships will disappear from the current battle and will trigger a failed after time has elapsed. (happens in stock game too)
(3) Need to go to the planet Hebridan site center to activate next mission after completeing the above 2 missions.
(4) one of the 2 missions (jobs) listed above are not completed.
(5) alteration of the credits through a cheat (please do not circumvent and alter the credits. It will mess up the mod.)
The most likely reason I think would be to see if there are any Besarain fighters left to destroy. Then the mission box will pop-up and tell you to go to the planet Hebridan. Did you get the mission box pop-up that says to go to the planet Hebridan?
I've played the Stargate Mod completely 2 times with no cheats and had no troubles and tested each job multiple times when making the mod. I am not saying that it's perfect since I am human myself. I know I didn't get all the out of context phrases and spelling even though I proofed eveything and also used spell-check too. Also try and make multiple saves if you run into a failed mission situation, then you will have game restore saves to fall back on.
If this still doesn't help we can force the trigger to occur. This would be the last resort. You could press ~TRIGGEREVENT EVENT GENERAL HAMMOND 13D~ but you should be very carefull of that since it may mess up the credits and you may have trouble with the rest of the mod. I would only use this method if the following mission (job) says failed:
Destroy all Goa'uld & Besarian Ships in the Hebridan system. When all enemies including Baal's ship are destroyed, go to the planet Hebridan (Failure is not an option-Repeat if Failed)
As far as the graphics go, my main pc is adequate to play any games I have. It is far from new. It has a single processor and decent graphics card. I have not had any trouble with any other games I own including Oblivion. But with Starfury I will get invisible ships/planets, etc. sometimes. It happens in the SF stock game too. My guess is that it's something in the SF game-engine. If a person was to have the SF source code they might be able to improve it. I really don't know for sure. So I just roll with it and when a ship is invisible, I pretend that it's cloaked.
I've included a picture attachment to show you what the Mission box display should look like. Enjoy the mod and keep me posted on how it's coming.
