want to start making scenes on Arma?
Here is one place to start

These are the bare minimum mods you will need:

[] Enhanced Artwork Supporter
[] POLPOX's Artwork Supporter
[] POLPOX's Base Functions

Not required but suggested:

[] Fifty Shades of Female (Adds women heads to Arma 3)

Mods that add to your pool of animations:

[] Whiplash Static Animations
[] nikoaton's Animations Pack
[] Movie Based Animation Pack
[] Pack Animation

In this, you will learn the basics of setting up and taking your first picture:

1] Start Arma and pick what mods you want to use

2] Enter the editor and pick your map

3] Set up the scene props

4] Start placing your Units
Under module it is called "Unit Animator" I believe

5] double click your unit and gear them up
Arsenal lets you set a custom loadout, Under that lets you pick from preset units

6] Find your animation
Under Tools, you can open the Animation Viewer (Alternatively use Ctrl+Q). Find a animation and copy it (CTRL+C)

7] Apply your animation(s) to unit(s)
Double click on the unit animator again, and apply the Animation to the Animation textbox

(Optional) Pick a Emotion
i.e. "Dead" should be used on units that are dead

8] Open the Enhanced Camera
Under the POLPOX section

9] Tune your camera to a liking, once you are ready, press "BACKSPACE"

10] Finally, move your cursor off screen, and Press F12

You have done your first artwork!

I made this quick video on how to give the units animations, its not perfect but it works.
