As part of my education at SiNTLUCAS I was tasked with learning how to use Substrance Painter.
To do this my classmates and I had to attend special classes every Thursday where we were given instructions by our teacher, after which we each had to create our own custom figurine by painting over a 3D model of a little doll called Meet MAT.

Here you can see the process of my work:

First I downloaded the official 3D model of Meet MAT from Sketchfab, imported it into Substance Painter and baked the mesh maps at a resolution of 4096x4096.
I chose for this resolution because I was planning to add a bunch of very small details later on, which would otherwise not be visible.

I then added a yellow base color to both the head and the body, applied a roughness variation layer on top of both of them, and applied one of the default concrete materials to the base.

Next I combined a bunch of different edge wear and scratches layer masks together and applied them to both the head, the body and the base, after which I also added a new damaged concrete material to the base underneath the default concrete material so that it would show up through the layer masks.
I then proceeded to do the same thing for the head and the body by applying a damaged plastic material in a darker color underneath the yellow base color, which would also show up through the layer masks.

After that I created a new layer above the yellow base color, but underneath the layer masks where I then painted on a bunch of crash test logos by using stencils with a black color.
I also added a black rubber material to the feet which I applied by selecting the faces of the mesh and painting over it with a new default rubber material on a separate layer.

Once that was done I created a new layer on the head where I painted a silly little face using a bunch of realistic paint brush brushes in order to make it look like the face was actually painted on by hand by a real person.
I also added a bunch of vague black smudges on top of both the head and the body for extra detail and to make the crash test dummy look like it had been hit by a few rubber car tyres.

Once I was happy with how everything looked I exported the texture into several different image files and sorted them all into their own folders.
The accessories folder contains image files that are going to be used in a later assignment, so just ignore that one for now.

After that I imported the original 3D model into Blender and combined all of the necessary image files together to create three separate PBR materials for the head, body and base.

Here is an example of how I put the image files together to form a PBR material for the body.
I set all the image files that didn't use any colors to Non-Color and I combined the normal map and the displacement map together for extra details.

After everything was finished I added a camera and a couple of lights to the scene, after which I let my laptop render four separate images of the crash test dummy.

Here is the final result.
I rendered each one of these images in fabulous 4K so that you can zoom in and appreciate every small detail.
