Videos on installing and using KIT OPS:
KIT OPS is a FREE is a Blender 2.8 addon that uses the systemized application of .blender files, called KIT OPS INSERTS, stored in folders called KPACKS, to instantly cut and add to existing objects or create standalone objects with the goal of rapidly creating and exploring new designs. It will work with any KPACKS which are purchased separately.
Because Blender Market has to charge something, this FREE version is being sold for $1. A 100% free version is available at https://gum.co/kitops
The application of different model parts is typically called “kitbashing” and takes its name from the early application of plastic model kit parts to larger scale models for the movie industry. The original Star Wars model spaceships were created in such a fashion.
When used properly, KIT OPS can create objects and scenes with extreme efficiency and speed. Doors and windows can be inserted and cut through walls. Complex industrial designs can be generated in a single sitting. KIT OPS uses the power of the Blender Modifiers to accomplish all of this.
KIT OPS comes with it's own manual, and a set of basic INSERTS you can use. Future INSERT libraries, called CATALOGS, are and will be forthcoming and will include architectural items (windows, doors, furniture) as well as control panels, screen graphics and more.
