Description:
Proper Aiming is fixing the crosshair aiming with Bows or Spells. The arrows goes right to the crosshair. To see examples of how it works in vanilla and then with Proper Aiming see the video at the end of description.

Known issue: it doesn't work with constant spells such as Flames, Sparks or Wall of Flames, etc... The rest of spells works fine!

Install:
Extract in your Data folder
Enable Proper Aiming.esp in SkyrimLauncher.exe
Go to section Highly recommended and follow the instructions. They are optional but helps with arrow gravity.

Uninstall:
Disable Proper Aiming.esp in SkyrimLauncher.exe
Delete Proper Aiming.esp from your Data folder.
IF you have included the lines from Highly recommended, I recommend you delete them as well.

Highly recommended:
Add the following lines in your Skyrim.ini found in My Documents\My Games\Skyrim for better arrow gravity:

[Combat]
f1PArrowTiltUpAngle=0.7
f3PArrowTiltUpAngle=0.7
f1PBoltTiltUpAngle=0.7
f3PBoltTiltUpAngle=0.7

Troubleshooting:
Problem: It doesn't work!
Solution: Move the mod at bottom load-order. Certain mods modifies the same parameters as this one and gets overwrited.

Note: if you have other lines such as the ones with Magnetism, remove them at least until you are done with this mod.

Short advanced explanation of how it works:
"This mod fiddles with auto-aim to make crosshair aiming work like it should with a drawback. Bigger auto-aim on big targets. But on smaller targets should be null or barely visible. Anyway, it's not perfect, I know, but that's the best I could get with tweaking the values.

Note that I tried to disable auto-aim while doing this, but it's really not possible without breaking crosshair aiming."

Changelog:
