Had get the first Displacement Map ready to run for the Lookdev Progress. The first Displacement Map is call Warped Map. It adds in a natural feel for Hard Surface especially Metal subjects. It creates an uneven look to the surface reason because a used Hard Surface subject does not contain flat surface anymore. It could have been bent,pressed or maybe absorbed a strong force on the surface before.



After the first Displacement Map was ready, the next was getting the first Specular Map out as well. With those two maps,moving forward with Basic Lookdev progress with at this time. There will be in between revise for some Maps during the progress for better result.
For now, try to get the Lookdev+Texture as close as to the reference. And apply some Artistic Sense later on.
