Satisfying and nostalgic, two words I kept in mind while constructing this cozy wooden marble course. Inspired by real toys and motivated by creating a virtual sense of play, the individual pieces are built on a fully modular grid system.

A solid foundation was required to ensure the marbles behaved consistently. Since Blender's rigid boy simulations are unreliable at small scales, I tweaked the sizes and dimension of the tracks until I got smooth, predictable results. From there, I modelled dozens more block variants and features that I felt would be interesting to showcase when used in the final contraption.

After the physics and pieces were in order, I began feeling out the look of the project. The base wood material was sourced online, but I wasn't satisfied with it. Adding my own bump and roughness maps gave the blocks a more matte and grained appearance. I also tested various HDRI and lighting set-ups in order to best showcase the new wood material.
While assembling the marble course, I kept camera shots, visual weight, and clarity in mind. Virtual cameras helped me get a variety of close-ups and unique angles that fully immerse the viewer. Choosing only still shots further highlighted the movement of the marbles.

With the addition of a quaint piano score, well-timed sound effects, and many hours of rendering, the final video came to life. I was proud seeing the project crystalize into something so close to my initial vision, and into something that is easily repurposed in the future.
