3D objects in visualized constructions are often created from 3D Cad. These 3D objects usually consist of copies of a number of basic details used to build a machine or construction. When exporting and importing from 3D cad to the visualization environment, duplicates of in-depth details are created, such as screws, nuts, plates, and more. This is done because a single detail in the 3D cad can be represented by the same detail but that it is located in several different places. In the visualization programs, the same detail must be created for each location where it is actually located. This creates an incredible amount of 3D objects / details.
Placing the right material in the visualization program on all of these items / details is a time-consuming job. Some details can also be removed, which will not be shown in the image.
With the Addon Simple Material Replacement, I have automated this process. This addon reads the name of each imported object / detail in Blender and sets the correct material next to a previously created database. There is also an option to highlight the details that can be deleted to speed up the rendering time in the program.
