About the Developer
About the Developer
Hi, I’m David McPherson, an independent developer focused on building productivity tools for game designers and 3D artists.
Modular Window Builder began as a personal solution during the development of my own game, I needed to create a variety of windows and doors, and the repetitive process quickly became tedious.
So I thought, “Why not build a tool to streamline it”
As the system grew more powerful and flexible, I realized it could save time for other developers too, and I then decided to polish it up and make it available to the wider community.
This is just the beginning. I'm actively working on expanding the tool with a Profile Designer for custom shapes and styles, and later, support for doors and sliding systems, all designed to integrate seamlessly into the same workflow.
