Unfortunately no, it’s not likely that I will be updating this course for 2.9. The value of the material is less the specifics of the software / version used and more of the conceptual workflow. Concepts can be applied to any software / version which is why we keep it published. One day if 3D animation standard workflow changes significantly we will remove it.
Blender changes too fast to re-record courses for each new version. All instructors within and outside of CGC have to deal with this curse / blessing. That’s why you rarely see us re-record a course 1-for-1. However we will sometimes record a new course focused on the same material with different visual focus. So it’s possible in the future we will record a new course about short film production using different characters and scenario than Piero.
