This project presents a complete 3D packaging design and product visualization developed for the fictional brand Crumbalicious, focusing on creating a premium CGI packshot of a metal cookie tin using Blender and Substance Painter. The process began with precise 3D modeling in Blender, where I built the tin with clean topology, smooth bevels, and realistic proportions to ensure a high-end product look, followed by the development of a charming cookie mascot designed to reinforce brand identity and emotional appeal. After modeling, I performed accurate UV unwrapping to optimize texture placement and resolution efficiency, then moved into Substance Painter to craft realistic metal materials, subtle surface details, embossed typography, and decorative dotted patterns that enhance authenticity and visual depth. AI-assisted research tools supported the reference-gathering phase to improve realism and production efficiency. The final stage involved professional lighting, shading, and photorealistic rendering in Blender, carefully highlighting reflections, material contrast, and branding elements to produce a high-impact 3D product rendering suitable for advertising, e-commerce, and digital marketing, demonstrating expertise in 3D packaging design, CGI product visualization, metal surface texturing, and brand-focused 3D presentation.
