Kitbash libraries can be an efficient way to save time when producing quick concepts for a mood piece, creating objects for background set-dressing, or adding detail and the indication of functionality to hard-surface models. In this workshop by Gavin Manners, you’ll be taken through the process of how to design and build your very own hard-surface kitbash library.


Gavin’s workshop begins with how to spark the initial idea and write a brief for yourself. He walks through gathering references to be properly prepared for the creation of the assets in Blender. Also covered is how to get the most out of your kitbash parts by creating subassemblies, as well as the principle of exponential idea generation.


The workshop then details how to create mech designs based on the brief, explaining how to use your custom kitbash library as effectively as possible. A simple lighting and rendering setup is also demonstrated before moving on to the final paint-over process to produce a finished piece of concept art.


The focus of this workshop is specifically on mechs, but the principles can be applied to any form of hard-surface design. By the end of the workshop, you’ll be able to create multiple personalized kitbash libraries and add to them over the course of your artistic career.


Although this workshop is for anyone with an interest in hard-surface design, it is not a beginner’s software tutorial; there is an assumed level of knowledge of Blender and Photoshop, so you will need to know the basics of the software.


Included with this workshop are the kit created for this tutorial, the mech design 3D files, and the final paint-over PSD files, so you can take a closer look at everything created throughout the process.

01Writing a Brief & Reference GatheringFree

In the first lesson of this workshop, Gavin Manners explains that successful kitbash creation relies heavily on thorough preparation and focused direction. By establishing clear design parameters through the strategic use of real-world references, artists can avoid common pitfalls such as scope creep and derivative work.

Duration: 9m 10s

02Creating Kitbash Assets Using Blender

This lesson presents an accessible hard-surface modeling workflow that prioritizes simplicity and efficiency over technical complexity. By focusing on a few core techniques, Gavin demonstrates how to build a functional kitbash library for mechanical design without needing advanced modeling skills. A strong focus on experimentation, real-time editing, and generating variations from base shapes makes this approach particularly suitable for concept artists and designers who need to quickly produce diverse mechanical assets for future projects.

03Texture Atlas

Gavin demonstrates a hybrid approach combining photo manipulation, procedural techniques, and manual painting to create realistic, detailed textures for hard-surface modeling. The process requires significant time investment upfront, but pays dividends by creating reusable assets and providing a solid foundation for final paint-overs. The combination of careful texture atlas preparation and shader complexity produces materials that effectively convey scale and visual interest while remaining paintable in post-production.

043D Scanning Techniques

In this lesson, artists will discover an efficient workflow for transforming everyday objects into versatile design assets through 3D scanning and creative manipulation. The key insight is that scanned objects are just starting points and Gavin explains how experimentation can yield multiple unique shapes from a single scan. This approach emphasizes discovery through trial and error, resulting in a rich library of elements that will ultimately be used for mech design in subsequent stages.

05Subassemblies

Effective mech design isn't only about creating perfect parts from scratch, but rather building a versatile library of sub-assemblies that can be combined in countless ways. Gavin highlights the power of exponential idea generation: the more high-quality assemblies the artist creates, the more design possibilities emerge from combinations and modifications. By balancing experimentation with intentional iteration, designers can develop a robust toolkit that makes subsequent design work faster, more varied, and more creative.

06Mech Design & Iteration

By maintaining a flexible, iterative approach and building a family of related designs, Gavin shows how kitbashing enables the rapid generation of multiple variants with a consistent visual language. The process emphasizes that the goal at this stage is generating compelling visual designs that read well from a distance and can be further refined through digital painting or additional modeling.

07Lighting & Rendering

In this lesson, Gavin demonstrates how maintaining a library of reusable parts enables rapid exploration of design variations, while emphasizing that scale consistency and visual coherence across designs are more important than rigid adherence to initial concepts. The approach balances technical precision with practical efficiency by focusing on effective solutions and planning for Photoshop refinement.

08Photoshop Mech Design Paintover

This paint-over process demonstrates how to transform a 3D render into an expressive, believable concept design through thoughtful simplification and refinement. Gavin's approach prioritizes design readability and manufactured believability over technical perfection, using atmospheric effects, decals, and weathering to create depth and narrative. The workflow shows that successful digital painting often means strategically refining detail, with the final result feeling cohesive, functional, and grounded in real-world mechanical design principles.

09Conclusion

This final lesson in the workshop reviews the benefits of building a comprehensive kitbash library that enables exponential creative possibilities and significant time savings in future design work. Gavin's systematic approach of creating modular, textured parts that combine into sub-assemblies teaches artists how to rapidly iterate and explore multiple concepts. While focused on mech design, this methodology applies to any hard-surface design work, making it a valuable addition to any 3D artist's workflow.
