From Blender to Unreal Engine 5 Character
First video in a series that explains in detail how to create a character in Blender (4.5.4 LTS) and export it correctly—complete with a skeleton—into Unreal Engine (5.6.1), including PhAT and support for animations created with Rigify.
All the plugins used in Blender are, at the time of publication, free, except for QuadRemesher, which can easily be replaced with manual remeshing or the native remesh tools.
