After creating my gas mask and helmet i decided that it would be a good idea to create a backpack for my character, this relates to the era well as many soldiers carried them to carry supplies, ammo, food and more. To make it fit in with my character i decided that i want it to be roughed up and torn in some parts to it goes together with the aesthetic of the character well and doesn’t look out of place.
Firstly I masked the area on the back where the backpack is going to be located.

After this i used the move tool at the top of the lightbox to extrude the masked out area to an appropriate distance from the body.

I then began by giving some rough detail to the backpack to define its shape before, I’m going this because I want a shape to work off when I go into detail so i know where to add more or less detail.

Extrusions to create new levels of backpack.
I decided to give the backpack multiple levels as that will look more like ww1 backpacks did. instead of modern ones without many layers.

I creased the backpack to give some texture to it.
After this i then added a cylinder to the backpack to create a big sleeping containing area for items which soldiers would want.

I then shrunk down the cylinder a bit and then started to smooth it out and smooth out the edges, creating a more realistic looking cylinder for the backpack.

I made some straps for the backpack so it isn’t suspended off of the back of the character.
