The character animation is created in Cascadeur, the fluffy hat (UE4 Hairs) is created in Blender, and a my Free Simple Fur material for UE4 is used to dress the character.

In making this video, I used my Blender addon Cascadeur to Game Engines to transfer the animation from Cascadeur to character.

Cascadeur animation file (cascadeur_to_ue4_demo.casc) and all other resources (fbx's, textures, etc) are located in the "ObjectsSources" folder.

Character is rigged with the Auto-Rig Pro.
