Day/Night Cycle mod for Jurassic Park: Operation Genesis

This mods adds a day night cycle into your copy of Jurassic Park Operation Genesis!

Contents:

• Edits to the mission files to enable the day/night cycle
• Custom lighting and Reshade preset
• New skyboxes for all 5 weathers
• Edits to the Constant.ini which include camera tweaks, increased lightning during storms, and dinosaur behaviors (dinosaurs will now get sleepy during twilight and during the night)
• Improved water texture
• A new track that plays during the clear night weather

Known Issues:

• This day/night cycle works with SiteB mode as well as the following exercises: Open Range Safari, Jurassic Classic, Lost World, Danger Abodes, and Any Port In A Storm. I did my very best to try and get this into the Operation Genesis mode, but alas I don't believe it is possible (Edit 8/31/24: currently trying to come up with a workaround for this, stay tuned)
• Since we cannot add weather, the tornado weather was cut in order to create the clear night weather. To make up for this, thunderstorms have been made more dangerous with a much greater chance of lightning striking buildings and fences.

Installation:

• Back up all of your files!
• Drag the contents of the mod folder into your JPOG folder and overwrite any files
• Boot the game up and have fun!

Operation Genesis Mode Support:

This version of the mod allows the day/night cycle to function in the campaign mode. In order for this to work, some significant fiddling was required; the result is completely functional but does take some work on the part of the user to achieve full functionality. The Site B mode of the game had to be moved into the exercise menu (it's after "Any Port In A Storm") and because of this island generation is no longer possible automatically. In order to change the shape of the island you will need to use the "Island Generation" menu option (it's in the place where Site B used to be on the main menu) to generate an island, then save it and change the island files of the edited mission (DinoOri) in order to match your newly generated island. This is a bit complex and janky so it may not be to everyone's tastes; however, without changes to the engine of the game this is the best we can do if we want a day/night cycle in the default game mode.

Installation of OG Mode Support Version:

• Back up all of your files! This is extremely important because this version comes with an edited SimJP.exe file. I suggest keeping a vanilla copy of the game somewhere on your PC
• Drag the contents of the mod folder into your JPOG folder, when the game asks you to overwrite files, click yes

To change the island in the new SiteB mode:

• Select the "Island Generation" button on the main menu (as mentioned above, it's in the slot SiteB mode used to occupy).
• Generate your island and save the game taking care not to overwrite the file named "Exit to Main Menu"; more on this in a bit.
• Exit out of the game and copy the S00, S01, and S02 files of your newly saved island. Make note of the original file name of the save file (my suggestion would be to paste the name into a text file so you won't forget)
• Rename those three files "DinoOri" and drag them into the "Islands" subfolder of the Mission folder and overwrite the files
• Find the DinoOri.SAV file and open it. Right at the top you will see the line Name = " ". In the quotations type or paste the original name of your newly generated island. Make sure you still have the ; after the quotation
• Save the file and now you can enter the game and play in SiteB mode with that island!

Known Issues:

• The tutorial mission, "Dino Origins" has been sacrificed in order to make room for the Site B mode.
• Site B mode does not automatically support island generation (it has to be done manually using the instructions above)
• For whatever reason the game really doesn't like running Operation Genesis mode in this manner and when exiting out to the main menu the game will crash. If you wanted to just quit to desktop this isn't a huge deal but if you wanted to go back to the main menu this can be an annoyance. To get around this I've included a dummy save file called "Exit to Main Menu"; when you want to quit out of your Operation Genesis game mode back to the menu, load up this save file and quit from it. This will get you to the main menu without crashing. All other functionality is in working order, it's just when trying to quit out does the game crash.

Template:

This is an add-on file that simply includes SiteB.mis file and edits to the Weather.ini. This is a blank slate of the mod and is intended for those who only want the mod without the cosmetic edits, or for people who want to incorporate a day/night cycle into their own mods/creations. You have full permission to use the template files for whatever you desire with the understanding that you will credit me somewhere.
