Marvelous Designer is quickly becoming an industry-standard software for creating character clothing and cloth simulation in environment art. Erika Lochs is a principal character artist who uses Marvelous Designer heavily in her professional career and strongly focuses on anything fabric-related.  This introductory workshop is for artists who have never used Marvelous Designer or are relatively new to the software. Erika’s complete introduction covers the essential features in the 3D and 2D windows and details everything you need to know to get started, including how to navigate Marvelous Designer and how to use avatars.  With all the basics covered, Erika then demonstrates how to create a basic denim jacket, working with a pattern provided. Artists can follow along with the workflow from start to finish. Additionally, Erika provides a bonus tutorial tailored for environment artists, focusing on creating a mediaeval tent.
