From Blender to Unreal Engine 5 Character Second video in a series that explains in detail how to create a Character in Blender (5.0) and export it correctly, complete with a skeleton, into Unreal Engine (5.7), including Phat and support for animations created with Rigify. All plugins used in Blender are, at the time of publication, free, with the exception of Quadremesher, which can easily be replaced with manual remeshing or the built-in option.
