Enabling FlyCam for LE3

Introduction

A small tutorial on how to enable FlyCam in Mass Effect LE3.

MAKE A BACKUP OF THE GAME VIA ME3TWEAKS MOD MANAGER BEFORE DOING ANYTHING.

Go to Tools > Generate New DLC Mod (Starter Kit) > Mass Effect 3 (Legendary Edition)
Fill out the form with any info you want, keeping in mind the Mount Number. This must be unique.

In the Mod Manager, righ-click your new mod and select Open Mod Folder.
Inside DLC_MOD_MODNAME > CookedPCConsole, drag the Default_DLC_MOD_MODNAME.bin onto the Mod Manager. You should now have a folder with the same name.
Move it into the root of your Mod folder (click HERE for a vidoe showing this).
Make a copy of Default_DLC_MOD_MODNAME.bin and move it to the root of your mod folder also (alongside the new folder you just moved).
Inside Default_DLC_MOD_MODNAME, open BIOInput.xml.
Below the following block of code:



<Section name="configuration">
    <Property name="basedon" type="0">..\..\BIOGame\DLC\DLC_Shared\Config\DefaultInput.ini</Property>
</Section>

Place the following lines:

Save your file.
Drag the file called Default_DLC_MOD_MODNAME.xml onto the Mod Manager. A new Default_DLC_MOD_MODNAME.bin will be created (click HERE for a video showing this)
Drag this new bin file into DLC_MOD_MODNAME > CookedPCConsole and overwrite when asked.
Install your mod per normal.
Enjoy FlyCam
