Rig in 5 is an addon designed to facilitate the process of separating the parts and renaming of a car type model that you download from the sketchfab page in a quick and easy way in just 5 steps you will have a car ready for animation. The addon has an internal implementation of rigacar to make the process much simpler and in a single panel.

1) import your model from the addon panel itself.

2) quickly relocate it to the center. 

3) adjust its orientation in a fast and precise way. create the names for both the model itself and the collection in which it will be stored. separate the wheels in a way never seen before. set the course for the center of mass of the car according to the most convenient component and clean and order everything with a click.

4) assemble the armature of your processed model. faster than ever.

5) generate the controls and your car is ready to animate.
