Learn how to develop a character concept from a rough sketch to a final render, using Blender for the 3D modeling and rendering and Photoshop for the final post-production work. This 3.5-hour workshop by art director and visual development artist Francesco Guarini is ideal for intermediate artists, though beginners can easily follow along and enjoy some Blender basics.  The workflow demonstrated in this character-focused workshop covers the basic principles of character design in Photoshop and how to translate a design in 3D using Blender. Francesco discusses the importance of considering functionality during the design process and always being mindful of how your design will affect the modeling, rigging, and animation departments.  This comprehensive tutorial is recommended for artists looking to incorporate Blender modeling into their character design workflow, though the techniques taught can be applied to any design workflow. Project files supplied with this workshop include Francesco’s design, model, and render files for subscribers to learn from.
