PROTOFACTOR Inc is a Southern California studio specializing in original, production-ready 3D assets for game developers. We design and publish royalty-free creature, character, and monster packs that are fully rigged, skinned, and animated with PBR materials, ready for Unity and Unreal Engine.

Our library focuses on distinctive fantasy, science-fiction, and horror designs—hybrid creatures, mechs, and unique anatomies built for real-time performance. Every asset is created with industry-standard tools and delivered in formats that drop straight into modern game projects.

From individual models to full packs, PROTOFACTOR provides high-quality, consistent art that helps developers bring their worlds to life faster.
