In order to bring the textures from substance painter into Maya and apply them to the model for rendering, I used the Arnold renderer. For this, I started by applying an Arnold standard surface material to the barrel.

From here, I could input the texture maps into the subsections of the material. I found Maya to handle this really easy as a lot of the sections were easy to find and allowed for me to easily input the maps.

After this, I added an Arnold skydome light. This provided a plain white background for the renders as well as evenly lighting the model. For the render settings, I used png as the output with Arnold renderer being selected for use.  I also selected 1920x1080p resolution to provide a high quality still to display my work.
