These will already be available via the Material Editor Palette. The material in the example was Unlit and had a Translucent renderstate. UE4 Material Blueprint Numerical Vector Parameters / Constants and Colors are one and the same, which makes perfects sense, since in computer graphics colors are in fact 3D vectors, RGB quantities being equivalent to XYZ spatial dimensions (4D with an Alpha channel). You can do many things within the material editor that do not require you to re-adjust and re-import a texture. Double click it and choose a colour. Double-click the OcclusionRoughnessMetallic packed texture and in the Texture Editor, uncheck sRGB.

Using a different version during export may result in incompatibilities. The SceneTexture material expression has outputs for the size and the inverse of the size (efficient and useful for pixel offsets). To improve two sided lighting on materials that use a custom lighting setup. Note that the Dynamic Parameter expression updates with this new parameter name.
