Export character walk cycle animation from Blender 2.8 to Unreal Engine. Part 3 of 3.
In previous videos our walk cycle was created using 24 frames. This allowed us to get even spacing between the animation poses. Now we will resize the animation to 30 frames and increase it's playback rate to 30 fps for export to UE.
I also used Uefy Script to give this character an Epic Skeleton compatible bone hierarchy. If you don't have Uefy, the export will still work as shown! But the bone hierarchy will be different and animation sharing with the default mannequin becomes difficult.
IMPORTANT:
This character was imported into Blender with World Scale set to 0.01 as is usual when making characters with armatures for Unreal Engine. If you do not do this you might run into issues with the engine.
If you are exporting a character rigged with only Rigify (without uefy script) you should not rename the rig to "Armature". This will ensure you get a single root bone when importing to Unreal Engine.
Rig Name Explanation from Comment Section:
======================================
Unreal treats imports from Blender differently based on whether or not the armature has been named "Armature". If it is, the top most bone it finds is deleted. This is necessary because Blender adds an extra bone on export that we don't want.
Unreal also expects that there will be a single root bone in the armature and everything will be attached to it. If you use Rigify for your armature it will have multiple bones at the root and that fails to meet this standard. So as a workaround that extra bone added by Blender now becomes useful. We name the armature anything else and that top extra blender bone is kept. We again end up with a single top most root. While this kind of works, it can cause issues with root motion.
It really depends on what rigging system you are using and whether or not it is built on a single root bone. In my video the character armature was built with Rigify but fixed with Uefy Script. So I get a correct single root bone hierarchy and thus name the rig as 'Armature' to get rid of the useless blender bone.
