Notes

EDITOR OPTIONS

For Player Stats, press F2 or whatever key to open the inventory, then the values will fill in and you can change them.  This will allow progression and buying items, and changing how much you can carry, etc.

Unlimited Health:
Toggle on and the trainer will try to recover and health you lose to animal attacks or otherwise.

Unlimited Ammo:
Toggle on and when you fire weapons you have plenty of ammo.  If you have no bullets in the chamber, toggle this OFF then reload, before you toggle back ON.

No Reload:
Once the current weapon has ammo in the chamber or in the current clip, toggle this on and you will not have to reload it.  If you don't have any ammo in the chamber, RELOAD FIRST, then toggle on.

Steady Heart Rate:
Toggle on and your heart rate remains calm.  Helps with aiming and scope shooting.

Time of Day:
Toggle on and it's always noon.  Can be modified.

Invisible To Animals:
Toggle on and most animals will not flee or even know you are near them.  Perfect for hunting and getting views of the animals.  This is the option everyone has wanted since this game came out!  If you wish to fire weapons while in this mode, then make sure the other option is on.

Allow Shooting While Invisible:
If you have invisible activated, toggle this on and then you will also be able to fire your weapons and most animals also will not spook when you fire the weapon and you are invisible.

Mega Travel Speed:
Toggle this on and you can move much more quickly about the map.  Works best on flat areas and roads.  Note that you can be damaged if you are moving fast and fall or smash into things.  Best to use the No Travel Damage option with this.  The speed value can also be modified if you like for faster or slower.  Extreme speeds, the game is likely not able to keep up where you are or will behave erratically.  However, this option with the default speed is likely to get you where you need to be in a very few seconds, where it would take a long time, even with vehicles, to reach.

No Travel Damage:
Toggle on and you cannot be hurt when falling or travelling.  May help with other forms of damage.  Best used when Travelling.  Also, toggle back OFF when not travelling and after you take a shot at animals.  This will prevent you from collecting them when you kill them, so if you cannot collect an animal you shot, toggle this off.

Super Lookout View:
This powerful option is best used when you:
1) are already in the area you wish to hunt and see tracks or are hearing animal calls.
2) are not going to move long distances
3) plan to hunt specific animals in a specific area or are tracking something that has left tracks very recent and is likely in the area.

To use it, make sure you are likely near animal(s), then toggle it on.  You and the animals in the vicinity are instantly teleported a distance into the air.  You can see where they are and also you have a bird's eye view of the area around you.

This option is best used to locate animals for final tracking, then toggle back off and head towards them.

You CAN shoot them while this is on, which may also help in hunting certain animals.

Best left OFF when travelling large distances and when first entering an area where animals may not have spawned quite yet.  It's best to wait for recent signs or animal calls.

You can also use this for just plain sightseeing.

Option value can be modified to go less high or more.

Remember, PROBABLY BEST NOT TO HAVE THIS ON WHILE MOVING AROUND FOR ANY LENGTH OF TIME.
