During this first week I
experimented with PBR materials, getting to grips with what different maps do
and how they all function together.
With the task of creating some materials,
I used some royalty free textures from ‘textures.com’ and then edited them in
photoshop to create the roughness, normal and metallic maps. I simply altered
the tone curve of the original images to get the black and white results I
needed to make the varying materials.
Importing them into Unreal Engine
4, I plugged in the texture maps and arranged some basic lighting to see how
the material would look. I could’ve packed some maps like the roughness and
metallic into the RGB of the albedo but for the sake of visually understand
what goes into a PBR I left them as individually maps.
