THIS INFO IS REDUNDANT WITH VERSION 2.0


In update 1.3 I have included a new INI file called "SkyrimMotionControlPerks.ini"


Introduction
This file has 2 Sections [Perks] and [Spells]

Within each section, there are attributes, where the Perk section has attributes that are named Perk1, Perk2, Perk3...
and the Spell section has attributes named Spell1, Spell2, Spell3.

The format would be:
Perk number = FormID|PluginName|MaxSpeedValue

Spell number = FormID|PluginName|MaxSpeedValue

EXAMPLE:

The Order of Perks and Spells are important, see it like a priority. Perk4 overwrites Perk1 if both are active. Same as Spells.
If 1 Perk and 1 Spell are active, the spell will overwrite the Perk value.

You can setup as many perks and spells as you like.


How to find out your Perk/Spell
You want a tool to easily check FormIDs of your desired perks/spells. I highly suggest using  sseEDIT.
Open up sseEdit and uncheck all plugins, except the ones that you want the perk/spell FormIDs from.

In this example we are using a Perk Ranger from Skyrim.esm, so we are unchecking all Plugins except for Skyrim.esm.

In the next step we are expanding the plugin on the left side where u also see "FormID".

Now scroll down until you find the section "Perk". There's your list of all Perks in that specific plugin. It would be "Spell" for all the plugins spells.
Now in the EditorID we look out for the name "Ranger". You can click on the "EditorID" tab, to make your life easier.
 

And the left column is already our FormID we need. Scrape the first 2 numbers, so u only end up with 058f63.
now take 0x + your number, so u end up with 0x058f63.
That's all you need for sseEdit.
Now navigate to the SkyrimMotionControlPerks.ini
And in the Perk section we define our new Perk.

Perk1 = 0x058f63|Skyrim.esm|10

So, if our Player Character now unlocks the Perk Ranger, he will only have a max speed of 10% of the MaxSpeed. You can set whatever value you desire.
